Roomba path long exposure photo

Paul Mathew at SignalTheorist.com attached an LED to the top of his Roobma and took a long exposure photograph to document the path the Roomba takes.  iRobot can tell you the Roomba gets into every corner, but it takes a visual like this to really prove it.

"Now here’s something interesting, I set up a photo camera in my room, turned out all the lights and took a long-exposure shot of my roomba doing it’s thing for about 30 minutes. The result is a picture that shows the path of the roomba through it’s cleaning cycle, it looks like a flight map or something. It really hits every spot!"
