roomba-movements

Signaltheorist did something really neat with a new Roomba he got. He shut off all of the lights in his room for 30 minutes and captured a long exposure of the path that the Roomba makes when it goes about cleaning the area. The resulting photo is a mess of circles and lines that somewhat resemble flight paths. I wonder what the paths would look like in a bigger room. I should get our Roomba out and see.
