With the new update, you can have different colours on beds. But what if (and this is kinda cool) you could make a banner, (maybe with a creeper head on) and mix it with the bed so you had a creeper (or whatever you put on to the banner) on the bed!
I get offtopic a lot, be warned. I also often mention a Minecraft clone called Minetest. The clone is nowhere near playable with it's default game in my opinion, but it's at least the start of a good open-source voxel rendering engine, and maybe one day it might be decently playable.
Hmm... I'm with you on the colors, but having them be like banners... Not that much. We don't need too much in it. If this works out, then maybe they'll add Banner-beds next. Other than that, I SUPPORT.
