Figured I might as well post this revamp of Red's generation 2 sprite I finished a few weeks ago. For reference, I used his original sprite and official artwork of him during gen I.

Probably the OCD thing like you said.

If anything, they're the ones who keep this community going, constantly releasing custom maps, mods, redstone contraptions, and the like.

This might make getting an Xbone perfect. All original multiplayers and a Halo 5 Beta? Time to start saving money.

Are you guys really falling for this? It is a thinly veiled attempt at advertising.

Yeah... That game. Got about 5 minutes into it before turning away and never looking back.

A topic springs to mind. Anyway, the community has been split since the 1.8 Beta update that changed the games mechanics quite a bit. I am not on the 1.8 side and still prefer B1.7.3 and before to 1.8 onward, minus command blocks. Let us not forget that the terrain was also a nice factor. A decent temperature system(Release 1.7 system, we get it.... You like to repeat biomes over and over...), nice mountains that didn't need sub-biomes to be generated, and so on. It's not nostagia blinding me, but the game's mechanics were fundamentally different, like the old health system. I only sacrificed 4 inventory slots for pork chops, and those would be depleted during long caving trips(oh yeah, most caves had an actual end to them), which were rare in B1.7.3 and before because most caves came to dead ends quickly. Remember the 404 challenge's cave? Those were fairly rare, compared to today.

The only reason I watch it is for the Pokemon themselves. I love seeing them, especially the new ones and how they look. I hate the characters and how they never....never mind, about went on a long rant.

Gettin' real tired of your crap, Ash.

Supporting this suggestion
Special thanks

[spoiler=Tl:dr]Q: Won't this increase lag?
A: Absolutely not. The title of this suggestion and big red letters at the top of this post aren't lying. If you want to know how, then I suggest you actually read this post.

Q: Will this change terrain? Will this break existing worlds?
A: No. Terrain change is not necessary. Existing worlds can be converted fairly easily with a process described later in this post.

Q: How can sunlight or rain work with infinite vertical space?
A: I suggest you read Coping with sunlight, because it's too complex for a tl;dr.

Q: I have a different question but still don't feel like reading this post. What do I do?
A: Too bad, read the FAQ. I put way too much work into this for the entirety of it to be ignored.[/spoiler]

Overview:

In Minecraft, the sky is the limit - literally. It doesn't matter how many thousands of blocks a player has traveled, or what dimension they're in, or even if they're playing in creative or survival, the highest they can ever build is up to a height of 256. Why is that? If Minecraft can have a world that's infinite in the north, in the south, in the east, and in the west, why can't that world be infinite up and down too?

In Minecraft's earliest days, in Classic and Indev, the world was not infinite in any direction. This was because the entire world needed to be generated at the same time, and the entire world needed to be simulated at the same time as well. This led to a conundrum - the bigger the world, the more it lagged.
Notch didn't like this. He knew his players liked to explore and build large creations, so he found a way to make the world truly infinite. When the Minecraft '' class='bbc'>Infdev came out, it brought with it truly infinite worlds. Suddenly, players could travel hundreds of thousands of blocks in any direction, and never encounter a barrier, or become too laggy.
The Infdev update brought about a very large change to Minecraft worlds to accomplish this feat. For the first time, instead every world being just a single huge piece, they were broken up into a two-dimensional grid of pieces, called chunks. Through breaking the world up into pieces, this 'chunk system' enabled infinite worlds by letting Minecraft create new pieces and simulate them only when it needs to.

Why does that not apply to the vertical axis? Because the type of 'chunk system' Minecraft uses right now is a linear one, which, by using only a two-dimensional grid to map out chunks, means that it is impossible for chunks to stack on top of one another, and by extension, meaning that a single chunk must cover the entire vertical space. This brings back the problem that the Infdev update was supposed to eradicate, now only with chunks, instead of an entire world; the bigger a chunk is, the more laggy it is. You can't just increase the height limit and make chunks taller, because it will become laggier, and laggier, and laggier to do it.
That's why, to fix this, Minecraft must change over to a cubic chunk system. Under this system, 16³ block chunks are aligned on a three-dimensional grid, completely eliminating maximum height as an aspect of lag.

The immediate benefits:
•Minecraft worlds become as virtually infinite vertically as they are horizontally: The absolute limit being Y = ±30,000,000.
•A large FPS increase: Alpha testers report an FPS increase of 100~200%.
•Increase in running capability: Computers running Minecraft on Tiny render distance will handle only 30% the blocks they do now.

The possible features:
•Spherical render/load distance: Reduce handled blocks by up to 30% by cutting corners made of unneeded chunks.
•Server chunk occlusion/exclusion: Reduce bandwidth usage and defeat hackers by only sending data for visible chunks.
•Three-dimensional biomes: Save biome data per chunk rather than per block column, create volcanoes with magma chambers, underground rivers, tropical skylands floating over icy taigas, and more.

The disadvantages:
•Unloaded gravity-pause: Falling non-player entities and fluids will be forced to pause their fall if they reach unloaded chunks, but will resume falling when those chunks are loaded.
•Slow falling-pause: Players with slower computers and smaller render distances will have falling occasionally paused as they fall into unloaded chunks, until new chunks can be loaded.

The problems:
•Current sunlight and rain calculation methods cannot work with infinite vertical space: The solution to this is described here.
•Current BiomeDecorator cannot work with multiple vertical chunks simultaneously: The BiomeDecorator code must be altered to function correctly with this, or removed.
•Current cave generation method is executed an extra time for each vertical chunk created simultaneously, leading to lag spikes on world generation: Cave generation's method must be altered to suit this system more.
•Current grass/dirt generation algorithm forces additional chunk requests when chunks are loaded, causing chunks to load slower than they should: This algorithm must be replaced with something else.

Changes in how things work:

Obviously, the implementation of this new chunk system will change quite a few things. These changes are mostly either necessary or in the interest of increased efficiency. Such changes are categorized and explained below.

How worlds will be stored:
[spoiler]How the current storage works, and what changes:
Interestingly enough, the current method of storage, the Anvil format, is derived from the storage method that the original Cubic Chunks mod used. The Anvil format stores individual chunk as a series of 16³ quasi-cubic chunks. These 'fake' cubic chunks allow for easier reference of specific data, but they still can't be separated from each other, meaning that it fails to reap the full benefits of this system. Even so, the change allowed Mojang to double the maximum height with no performance hit. Chunks are stored in groups of 32², inside 'MCRegion' files, for a total of 1024 chunks.
By nature, cubic chunks does away with the 'quasi-cubic' nonsense. In terms of chunk grouping, instead of using groups of 32³ chunks, new "3DRegion" files would contain groups of 16³. This means each 3DRegion file contains 4096 chunks, four times as many as MCRegion files. However, each 3DRegion contains only one fourth the amount of blocks. For per-chunk positional metadata, 3DRegion files would use the same number of bits as MCRegion files, after compression. Calculations show that the same area encompassed by a single MCRegion file would consume 64 kilobytes of extra space with 4 3DRegion files, which is nothing.

Converting existing worlds:
Most people are probably wondering something like "But won't this totally destroy all existing worlds?". Absolutely not; conversion could not be simpler. When a non-cubic world is loaded after the implementation of this system, a conversion process will begin and convert the entire world at once(To avoid making chunk loading take longer during play). First, all existing MCRegion files will be divided into quarters to create 3DRegion files. Then, all existing chunks are divided into sixteenths using the quasi-cubic properties to identify boundaries. After that, conversion is done.

The "isEmpty" flag optimization:
A 1-bit flag is added to each chunk, named "isEmpty". If the chunk consists of 100% air blocks, this bit is 1, any other case makes it 0. When the bit is 1, all data for the chunk besides the isEmpty flag is deleted and ignored, which reduces filesize. Empty chunks are never loaded, and locations where they occur are merely simulated as entities reside in them. The chunk will only load when something requires saving inside it.[/spoiler]

Changes to terrain, ores, etcetera:
[spoiler]Terrain:
By default, nothing will change. Small bits of terrain generation code need to be reconfigured to work properly with Cubic Chunks.

Biomes:
By default, nothing will change.

Ore generation:
By default, nothing will change.

Structures:
By default, nothing will change.

The Void:
After conversion to Cubic Chunks, the void and bedrock layer will still exist and generate as they always have. However, the void(Not the bedrock layer!) will not exist as a hard limit and is able to be moved, but not removed, by editing an associated NBT data tag inside a world's level.dat. This feature, that allows for increasing the maximum depth, is intentionally disabled without external programs, to prevent terrain change of any sort. It is intended to be used by experienced mapmakers and world generation mods only.

Superflat settings:
Existing superflat worlds will not change. However, new superflat worlds will gain a new decoration parameter, 'void'. Inclusion of this parameter will cause the void to form below the lowest defined layer. Exclusion of it will cause all layers below the lowest defined layer to copy the settings of that layer.[/spoiler]

Coping with sunlight:
[spoiler]There used to be a solution here, but it wasn't deemed good enough by Jeb. Suggest solutions in this thread.[/spoiler]

Changes to servers:
[spoiler]Settings:
There's a setting inside the Server.properties file called 'max-build-height'. The setting makes it impossible for any player to place or remove blocks above that height.
With the implementation of Cubic Chunks, a new setting named "maximum-generation-depth" would be added. The void, bedrock layers, and magma layers will generate normally at and above the Y level designated by the value of this setting.

Chunk occlusion/exclusion:
Using the raytracing methods already available in the code and used for explosion calculations, servers can identify which chunks are visible to a player, within safe assumptions, and only send the data for those chunks. This both reduces bandwidth usage, and cripples the usefulness of X-Ray cheats.[/spoiler]

Render/Load distance alterations:
[spoiler]After the implementation of Cubic Chunks, view distances' radii will apply to the vertical axis too. This reduces handled blocks in the cases of tiny and short render distances, and increases them in the cases of normal and far render distances. This can be optimized by utilizing a spherical render distance instead of a cubic one, which would reduce handled blocks in all distances except Far.[/spoiler]

Frequently Asked Questions:

[spoiler=FAQ]Q: This is impossible.
A: No it's not. See below.

Q: Is this available as a mod?
A: Not yet! But it will be!

Q: I like X-ray! What if I don't want it to be broken?
A: First of all, breaking X-ray hacks will only be possible to do in multiplayer. That said, the system that would break X-ray would be possible to disable by the server owner. If the owner doesn't disable the system, then they don't want you using X-ray, and you should not be doing what the server owner doesn't want in the first place.

Q: I play on a PvP/Anarchy/Raid/Faction server. Won't this system let people pillar up into the sky and create a base thousands of blocks in the air and never be found?
A: No.

Q: I like Minecraft's current height limits. What if I don't want to have an infinite sky or infinite underground?
A: If this system is added, all worlds will not automatically gain an infinite underground. As stated below, the Void will remain in all worlds, even after the conversion to Cubic Chunks. The ability to remove the Void will simply be there. As for infinite space in the sky, the current build limit is over one hundred blocks above any terrain that vanilla Minecraft can possibly generate. It is ENTIRELY your decision on whether or not you take advantage of this height. If you play on a server, like stated above, the server owner can set a maximum build height. If s/he doesn't, then don't play on their server - you don't play on servers where the server owners allow things you don't like. Why would you play on an anarchy server if you hate being stolen from and killed?

Q: Will this affect Redstone at all?
A: No. This system will simply make it possible to make larger redstone circuitry than before.

Q: Won't this break existing worlds?
A: No. Existing worlds can be easily converted by dividing each MCRegion file into 4 pieces, then slicing the existing 256 block-high chunks inside them into 16 individual chunks.

Q: Won't this affect mods? Won't mod authors have a hard time updating their mods?
A: The answer to this question depends solely on the answer to the following two questions: Do parts of the modification code rely on chunk data/metadata? Does the mod author want to take advantage of the features of the new chunk system? If the answers to the first and second question are both "No", then updating a mod to this system should be very easy and quick. If the answer to the first question is "Yes", then those parts of the code will need to be rewritten somewhat, but in most cases, the changes should be fairly quick and easy. The only time that it should be hard to update a mod to this system, is if the answer to the second question is "Yes".

Q: Won't this require a total rewrite of the mod API if that's released first?
A: No. Whether or not even a small part of the mod API needs to be rewritten depends on the way that it is implemented and whether or not there are API inclusions for chunk handling and other chunk-related behavior.

Q: Could a player fall into unloaded chunks if chunks aren't loaded fast enough?
A: No, they could not, and for several reasons. Minecraft has a terminal velocity, though it might not seem like it. This velocity is slower than it should take to load new chunks below the player. In cases with exceptionally slow computers, even if the player did manage to reach an unloaded chunk, their fall would be paused until that chunk can be loaded.

Q: What would happen when water, sand, or a mob falls into an unloaded chunk?
A: Nothing. The water/sand/mob would freeze in place until the chunk is loaded and it can continue moving. You can already see this same thing happening on the horizontal axis.

Q: What will happen to the Void?
A: It will still exist, along with all its effects. The only difference is that the Void is no longer a hard limit and it can be moved. After the conversion to Cubic Chunks, the Void's location will be stored in a world's ' class='bbc'>level.dat, and this location can be changed with NBT editing tools. When and where the Void exists, chunks will cease to generate.

Q: Will this affect terrain?
A: No. However, terrain generators will gain the ability to use infinite height.

Q: Will this affect ore generation?
A: No. Ore is a part of terrain generation. As stated above, terrain will not be changed.

Q: Won't all current terrain generators be incompatible with this system and need to be rewritten?
A: No. Terrain generators work independently of chunks. When a chunk is generated for the first time, it calls the terrain generator and receives a specific section of the resultant terrain to save inside itself. Because of this, some custom terrain generators can generate steep terrain all the way to Y256, where you can experience a large, flat cut-off. Since there are no chunks above Y256 to call the terrain generator for terrain, no terrain exists there.

Q: What would happen if there's a huge solid ceiling so far above you that it is unloaded? Wouldn't you just see the sky, just with everything being completely dark?
A: Yes. This already happens on the horizontal axis, and it is an issue with sky rendering, not this chunk system. As such, this has nothing to do with this suggestion. Please do not post about this.

Q: If you go deep underground, will your plants grow/ores smelt/animals grow?
A: No, because those chunks would be unloaded, just as if you had walked far away. This is a flaw with any chunk system, regardless of shape. It is a necessary evil that allows Minecraft to have infinite worlds. The only way to fix this would be to introduce a separate new system that works with chunks as they are loaded and unloaded. This suggestion deals with the chunk system itself, and not sister processes. Because of that, that is outside of the scope of this suggestion. Please do not post about this.[/spoiler]

[WIP] The Cubic Chunks Mod! (Tall Worlds Mod):

Cuchaz has taken it upon himself to bring us the glorious Cubic Chunks, since Mojang refuses to do so.

Cuchaz is using a API of his own creation to help assist in the making of this mod, and he's quite far along, as seen in these two tech demo videos:
[spoiler=T-Demo 1: Vertical chunk loading][/spoiler]
[spoiler=T-Demo 2: Broken height cap and no lag!][/spoiler]
With the basic functionality in place - a complete overhaul of the basic chunk system, and height limit removed - this whole concept can already be considered proven. What remains is making sure everything else functions correctly under the new chunk system. In any case, stay tuned for future updates if it interests you(If it doesn't, then you are the weakest link - goodbye!).

You can follow the mod's development in much more depth in its very own topic!

UPDATE 01/16/2014
Snapshot 14w3b introduces the ability to texture both arms and legs! It also gives every other body part an extra 3D layer similar to the hat layer in the original skin! Awesome! These new extra layers are covered up by Armor, just like the hat area. The new skin file uses a 64x64 layout with the old skin at the top and the optional overlays in the bottom half. Old 64x32 skins are still supported without modification.

However... this addition will not apply to similarly shaped mobs (zombies, zombie pigmen, etc) and it doesn't work on armor. Whether these things will change in the future is anyone's guess.

As happy as I am for the player improvements, I can't help but wonder if my suggested layout could still benefit the mobs and armors. If nothing else, it would still allow for asymmetrical mob skins and armor while staying within the small 64x32 file size. But then they would have a major discrepancy between formats...

I still like the idea of applying my format to the new skin layout - the bottom half of the 64x64 texture could contain the overlay regions. The only difference then is that the head and hat area on the bottom half would not be used. Perhaps those areas could then be left empty for modders and any other small additions that Mojang made add in the future....

What follows is the original post, while I decide if I should further modify it to try and push for the other mobs/armors to have asymmetrical textures. Either way, this is a huge victory!
Acknowledgement from Dinnerbone himself!

Quote from Dinnerbone

We've no plans to touch skins right now (except to fix them... the skin server is really unstable) but we're rewriting the whole rendering stuffs and maybe we can consider looking at this then, when it all becomes much easier.

Basically saying "maybe" in the future. The important part is that Mojang is aware of the suggestion and was moved enough to respond to the topic!

I am forever amazed with how much detail minecrafters have been able to squeeze out of the extremely limited space provided by the game's textures. Skins especially are quite a challenge due to being confined to a 64x32 pixel size. And yet there are many, many examples of beautiful and amazing skins out there that make the most of this limited space. And yet, it could be possible to grant everyone a little more... to be blunt, the current skin texture for the player character has a lot of unused and wasted space. For those counting, there are 480 unused pixels in the texture (out of a total of 2048).

With a little juggling, we could free up enough space to have independently textured left and right arms and legs! This is without changing the image size, it's still all contained within the same 64x32 png file. Of course, the player model would need to be updated to use this new mapping. Here is an enlarged view:
Pros:
+ independently textured arms and legs+ maintains the original 64x32 size = no additional skin server load/stress
+ keeps all sections grouped together in a fairly intuitive way.
+ sub sections follow a mapping very similar to the original (with only some parts slightly shifted)+ can also be applied to all armors
+ can also be applied to other humanoid mobs: zombie, pigmen, zombie_pigmen
+ can also be applied to skeletons - with slight modifications for the thinner arms/legs

Cons:
- one-time conversion needed for all texture packs for affected mobs and armors
- mods that make use of current skin's blank area may not be able to use the new format
- skin creation tools/viewers would need to update for the new format (difficult for discontinued tools)
- makes all current skins and skin repositories outdated (this is a big problem - see below)

Problem: Compatibility with Legacy Skins
There are hundreds of thousands of skins floating out there on the net. It is not reasonable to expect all of them to be updated or converted. Remember when they flipped the direction of the bottom-head/hat texture areas on the skins? There are still countless skins out there that haven't been fixed. This is a major change so it can't simply be done and let all the current content out there suddenly break. There will be backlash. On top of that, more recently the Minecraft Launcher has been augmented to allow easy access to older versions of the game - versions which absolutely expect the player skin to be using the old format. Finally, there is no reliable way to program the game to detect the different kind of skin formats based only on areas of the skin file that appear to be used. This is because the skins often have extra content in the "unused" areas. This content could be in the form of an author's name/logo, bleed off from the main image, or pixels used by specific mods on the skin.

Bottom line, we need to have a simple way for the game to know how to differentiate between the old and new player skin formats so both may be used at the same time by different players. Note that this problem only affects player skins. Mobs and armors are always controlled by the local texture pack, so there is no need to support the old format for those assets.

Below are several possible solutions to supporting the legacy skins. These are only suggestions, as I do not have intimate knowledge of how Minecraft and the skin system works under the covers. What I propose here may be incorrect or not applicable to the system, but I hope it might at least give Mojang ideas on how to implement this request.

Solution A: Increase new skin file to be 64x64
Increase the "new" player skin size to be 64x64 pixels. Place my new format in the top half and leave the rest blank. Let the old skins stay as using the 64x32 size. There are several reasons for this approach.

When the game client downloads the player skins, it can easily tell the difference in size. A 64x32 skin would use the traditional mapping we see today. Nothing changes and all the current skins out there are still ok to use. A 64x64 texture would signal the game to switch over to using the new format for that player. Since the game knows which player is using which skin, it can easily keep track of which format to use for who, and allow both types to co-exist at the same time.

The extra space in the bottom half of the "new" skin can be used for future player character enhancements by Mojang, in case they decide to add more. As an example... if we ever get custom capes, perhaps the texture could be saved to the player skin and use the extra space here.

The extra space in the bottom half of the "new" skin can also be used by mods! Any mods that had additions to the player model could use these areas. And there would be a lot more space now!

One major drawback to this approach is that the larger image file size could adversely affect the skin servers that Mojang use.

Solution B: stay 64x32 but use embedded metadata
If it proves undesirable to alter the skin file dimensions, another possible solution could be to have all new skins require metadata content added to them. Then, similar to solution A, the game would examine each skin file it downloads and search for the appropriate metadata flag. If it finds none, use the old formatting style on that skin's owning player. If it finds the appropriate metadata flag, use the new format for that player.

One problem with this approach is that png files don't have a standard way of encoding metadata. So I imagine Mojang would need to create a small utility to "stamp" skins with the metadata flag they would expect to use. This would require some extra care for making new skins on the part of the community. But on the up side, this could pave the way for an easy versioning system for additional future skin formats.

Another drawback would be the reduction in free space that some mods may have come to depend on. In this case, I believe the only solution would simply to have those mods not use the new style. They would have to require their users to say using the old skin format. So they wouldn't get the extra arm and leg, but the mods wouldn't break either. A fair trade off I think.

tldr Summary:
I propose a new skin layout for the humanoid mobs, player, and armor which would grant space for both arms and legs to be textured independently. It would be ideal to support both this new format and the old one at the same time for player skins - so as to not break all the current skins out there. There are two (possibly more) ways I can think of doing this:

Overhyped, overpriced, and over-advertised. If you like that kind of thing I guess you should get it, but honestly until it goes below 30 bucks (knowing COD games that would be never) it's not going to be bought.

They work because of combustible lemons.
