Eightbit.me is an 8-bit retro avatar builder, will eventually be a game
Facial detail is obviously limited with only a couple dozen pixels to work with for each character's face, so sometimes it comes down to the clothes when you're trying to make your avatar distinctive. That shouldn't be a problem in the Eightbit.me user gallery or in the mysterious forthcoming game, but it's a bit of a pain on Twitter. When all your friends have gone 8-bit, one brunette with glasses looks just like another.
I hope Eightbit.me turns into an amazing game, but I also hope people stop using their 8-bit characters' heads as Twitter icons.
