What charity you would give money to?

This is probably the "goon" answer, but I really like the Child's Play charity. The guys who make the Penny Arcade webcomic got tired of the stereotype that video games make kids go crazy and shoot up schools, and decided to make a charity that gives games, toys, books, movies to sick children in hospitals to brighten up their lives during a tough time. We're talking terminally ill kids, kids with cancer, etc. Basically gamers using gaming to help people.
Its turned into a rather large and succesful charity, they raise millions, get some nerd celebs involved, and so forth. They do a formal dinner that costs a good bit, and auction off stuff like a bronze statue that Blizzard had made for employees.
The charity itself basically "works" for nerds. You can paypal, or go to amazon and buy something off wishlists set up for the charity. Hospitals contact the charity, and I think they make a wishlist of the kinds of things they'd like to have. Its cool because I think most people can dig out 10-20 bux for a movie or video game for a childrens hospital. Then if you really want to go a bit further, buy them a Nintendo DS or a Wii, or just paypal some cash. Coolest charity I can think of.
So what about you?
