People love the Roomba. Why? Because it allows you to vacuum a room while sitting on the couch. Also because it seems more attainable than the Segway. And then a cat rode one, and it was glorious. Now comes something truly groundbreaking -- Roomba art. As far as we can tell, the trend started on a blog called Signal Theorist, who got the idea to set up a camera, turn off all the lights, and take a long-exposure photo of the Roomba's path as it "did its thing." The result looked like an awesomely psychedelic electrical spider web. Now more people are getting inspired to try variations on the same technique, and the creativity seems to be concentrated in the Flickr group, Roomba Art. Check out a few below, but be sure to head over to the group to see them all.
