I saw that Paint.Exe Challenge going around and really reminded me of a similar game called Broken Picture Telephone. Same concept. Start out with a written phrase. Someone draws that phrase. Someone describes that drawing. And it goes along for a certain number of rounds. It almost assuredly gets distorted in humorous ways. For the artists in the house, it'd probably be pretty great.
The only real downside is how long it takes for a game to finish. Seriously. Ages. But play enough and they'll start finishing and you'll get to see your handiwork come to fruition.
