Another sweet idea:
WebCollage is a program that creates collages out of random images found on the Web. More images are being added to the collage about once a minute, so this page will reload itself periodically. Clicking on one of the images in the collage will take you to the page on which it was found.
It also works as a plugin to DriftNet to see a collage what other people on your network are looking at. It's all good!
So, keep refereshing; you may see your picture there! :-)
