The vertical tower thing is somewhat inconvenient though. For example, you have to get the height exactly right other wise the current will either be opposite of what you need or will be one block above/below where you want it.
Plus, it can't go down.
Actually, you can get redstone to go down. May I present the following:
= torch on side of block
= block of choice
We have ways of making redstone go up and down but those solutions are... ugly. Not quite as ugly as booster cart mechanisms (no offense intended, but they are bulky. I support sticky redstone because it has more aesthetic potential for circuitry going up and down pillars.
While we're at it, sticky redstone should glow slightly brighter.
i like this idea a lot. useful for when (if they ever do) add on/off lights so i could put them on the ceiling.
what about this, though: when you craft things with the sticky redstone, it would make it also sticky. such as a redstone repeater so that it would stick on a wall. (i would look kinda ugly, but useful)\
off topic - how do you make the picture of the crafting square thing?
There are ways of making redstone go up, but now down on walls. I suggest that in addition to sticky redstone, sticky redstone torches, that can do the opposite motion that the upward inveter does, a downward inverter.
