I've been playing a lot of b1.7.3 recently. It's really a different experience, since there's no hunger bar or regeneration, no repairing items, etc. b1.7.2 was actually the version I first started playing, but b1.7.3 has less bugs. I'm using spoilers here because there's A LOT of images.
I actually went through a lot of seeds, trying to find the perfect place before dark. Eventually, I found a nice flat island that seems perfect, and it had trees in the shape of a smiley face! I didn't take any screenshots of me getting there but I do have one of my temporary house, which was just a hole...
Here's a better picture, taken much later. All this stuff is still kicking around, just to remind me where I started:
After I slept the night away, I made a little farm, and went out to try to find some coal and food on the surface, other things too that I probably forgot. here's the return trip after a successful search.
Around this time I explored a cave off the shore around my island, getting lots of resources, and I officially named the island: Smiley Island. Afterwards, I put a fence around my farm, since mobs love to trample and jump on crops here. I also used a lot of cobblestone from exploring to snap a photo of the entire island.
See? A smiley face! I planted the other trees.
Now here's some photos of me making the island spawn proof, and building my house, and greenhouse. I haven't actually tried building diagonally like I did here before, and I think it looks great!
A part that you actually couldn't see in the last picture, as that there's a peninsula. I named it the Chin Peninsula, for obvious reasons.
Planning the layout of the house. Note I didn't think of making the greenhouse yet.
Here's when I started planning the greenhouse too. (The GUI was a texture pack concept I was mucking around with)
Much later on I decided to start a 2nd floor of my house. Here's a nice view of the WIP:
Here's a tour of my (almost) completed base, I don't actually know what to put on the 2nd floor as of right now (Suggestions are welcome):
Atop the greenhouse:
The very top:
Main room (Those double doors connect to the greenhouse):
The greenhouse (Took this picture at a WAAAAAYYY earlier time than the rest of these):
Area right connect/right behind the main room:
Bedroom (Where the door above leads to):
2nd floor (Nothing up here yet like I said):
Entrance to my storage room/mine. The ladder behind me goes back up to the house, the stairs spiral down to Y=12 where my branch mine is, and going forward leads to the storage:
Storage room (The dirt/grass blocks are placeholders until I need more chests for that certain type, and no you cannot stack chests on one another or the bottom one can't be opened in this version):
An example of my spiral staircase down to my branch mine. It's a 4x4 staircase, and it looks like this all the way down until Y=12:
The main room of my strip mine. It has two tunnels going North and South (I could tell by the debug menu), and I keep count of how many branches each tunnel has:
Here's part of the North tunnel. What I do is that, every 4 blocks, I dig out 32 blocks out on either side. This has netted me lots of ores (and diamonds), and I pretty much do this in any world I play in. Lots of caves have gotten in the way this time:
Okay now for random screenshots I took, of random importance:
Mobs love to swim in the water surrounding my island (Especially Creepers, IDK why). This has pretty much persuaded me into just using boats instead of building bridges (Yup, pre-1.9 boats):
Rain falling on top of my greenhouse:
You've probably noticed the random oak/spruce trees planted about (like in the above picture). I basically plant a whole bunch of saplings along specific spots on the shore so I can get lots of wood. Here's a whole bunch of oak trees that I planted for the 2nd floor of my house:
Here's a picture when I went caving, and found my first diamond. It was a single-ore vein, sadly. I have since found a bunch more thanks to my branch mine, but it's still notable:
Here's a screenshot I nabbed of a thunderstorm happening:
That's about it so far. I haven't ventured in the nether yet, though I am perfectly capable to do so.
Here's the seed and coordinates of Smiley Island. This seed only works in earlier version of Minecraft:
Coordinates (X, Y, Z): 89, 65, 180 (Should put you in the middle of the island)
Thanks if you actually read all that.
