Texture Pack Your World!
Unfortunately there's no snapsho... oh wait, yes there is! Snapshot 12w39a where Dinnerbone fixed lighting bugs like they're nothing! Also Minecraft XBOX edition is catching up 1.8.2!
Installing texture packs:
Copy the zip (don't extract it) over to minecraft/texturepacks
HD Texture packs require either Optifine or HD Textures from MC Patcher
