ROS

I was wondering if anyone else has had any experience with the robot operating system. I have the mechanical skills of a two year old, along with no free time, but I got my old netbook's webcam to stream video to a face detector and output an indication when a face was detected after about fifteen minutes of work. I other words, it seems to be a very powerful set of tools. Has anyone else done anything interesting with it?

Face detection isn't too hard, you can probably do it in 15 minutes just with a raw video feed and an edge detect filter.
