Make a Snake game that we can play while downloading files.
there's already tetris... as if we needed snake. Most people I know prefer tetris over snake.
Make a drawing pad GUI. Make it a little central box and then players can pick their colors with RGB hex code. It's a good way for people to practice reading hex code anyways.
you could also make it so that the background becomes transparent but you can draw still, that way you can draw a mustache on badspot while he's afk.
sounds interesting, i'll think about it
mmorpg chat
sounds cool, this reminds me of an add-on i made called encode chat, and it would encode your text anytime you wanted. i could say some stuff, and to another person it would just seem like random letters, but to another person who had the mod, they could see exactly what i was typing :)
