Where can I find free sprites and images?
I'm teaching kids to program using Ruby and the gaming framework Gosu/Chingu. Kids love it, including the part where they have to look for the icons/graphics for their game objects.
I direct them to iconarchive.com, but the selection is sometimes very limited, the graphics aren't always with transparent backgrounds and sometimes the art requires payment. I don't mind paying for an educational license of some sort, but I want the kids to easily select graphics they can use in their games. Is there another resource better suited for this purpose?
I don't have a good solution for this, but would also love a site they can get cool background images for their games.
