I had a bit of an idea for a sort of charity-driven event as it seems like game-related charity is getting pretty big with the Humble Bundle, Speedrun events and such.
The idea would simply be that we get a bunch of game artists, be them pixel art or otherwise and livestream them making game art. This could be anything from tiles to sprites or something. They have no direction or goal, just to draw whatever they want. And as they livestream people can bid on the art and whoever gets the final bid at the end of the livestream gets a copy/rights to the graphics for their own use(I'd imagine in their own game or something).
I have never really been involved with any sort of charity event, and not even in the many time-based game development scenes like Ludum Dare's so I'm not sure how successful something like this could be, but it was just an idea.
Alternatively instead of going the route of having only one winner we could instead go the Humble Bundle route and have it where anyone who donates can get rights to the graphics. *shrug* not sure what would be the better one for raising money.
