A few nice change background image images I found:
SaveMe 3

Taken in Amsterdam 2 on 22 May 2011 at SaveMe Oh's "Screen Me" event. This is SaveMe at the center of the action. If you've never seen SaveMe in action, you have to imagine an environment with streaming media turned on, the background images are constantly swirling around, changing many times per second. No way to capture that in a photo. :)
