Found some more fun links:

Groverfield (http://www.youtube.com/watch?v=RQgTnJFFXvQ). (Should be self explanatory)

Tetris theme (http://www.youtube.com/watch?v=GkDBlEvfbgg)... played on bottles.

Elephant painting (http://www.youtube.com/watch?v=He7Ge7Sogrk) a self portrait. Really amazing.

That elephant's got skills! We just need to team him up with the chick with the bottles and we've got... uh... nevermind. That's a picture that only the Internet can paint. :D

I think I saw on Animal Planet, when it came self-portrait, the elephant was being guided by the handler.

However the freeform painting the animal did without the handler nearby was amazing as well...

Yeah... snopes has an article on it. Its trained to paint certain things and the trainer guides it as to what to paint next.
