Well, here it is! A long-exposure shot by an cool people:
It’s a result of 30 minutes long-exposure photo of the Roomba pathway while cleaning up. I’m not sure why the pathway color is orange, all I can say is the picture looks very good. A combination of a random lines and circles. It somehow looks like a crop circle left by Alien on the Corn Field.
