This really sheds some insight into animal intelligence. This painting was done by an elephant. You can watch it in the process in the following video. I have no idea how much training into this but this animal clearly has an idea of what it looks like and a sense of aesthetics.

It’s funny, this showed up on Digg and people there tried to suggest it was painstakingly taught to draw each line on verbal command but the video has accompanying audio and you can hear that no such commands are given.
