This 30-minute long-exposure shows the trail blazed by the blinking light of a Roomba as it goes about its autonomous, ceaseless duties. The photograph was snapped by curious blogger Signaltheorist to see just how effective the little vacuum-robot would be:
The picture reminds me of a documentary I once saw about spiders. The web-spinners were fed drugs of various kinds and then left to weave their sticky silk fly-traps. The results were fascinating -- cocaine webs were erratic and messy, cannabis webs meticulous and perfect and the LSD webs were just plain weird.
Signaltheorist seems to be an inveterate experimenter, too. While you're at the site, check out his video of carrots in a blender, shot at an amazing 600FPS on a Casio EX-F1.
