Ever wonder what path your Roomba takes as it clears the floor? Well, here’s an easy way to find out, and create some fine artwork in the process. The above pictures were made by sticking an LED to the top of a Roomba vacuum, then photographing it using a long exposure setting. This results in a form of motion capture, and you can clearly see where your Roomba has been by where the light trails are. There are a bunch of other photos at the Flickr group.
Now, if I was going to do this, I would also put a big light on my cat, so I can show how quickly it makes a b-line for cover when the scary vacuum turns on.
