Here is a video you might enjoy. It features a turtle riding around on a Roomba. I bet zombie kid would love seeing this one.

In the above video several iRobot machines are dressed up like Pac Man characters. The robots are dressed like Pac Man, Inky, Pinky, Blinky, and Clyde. The robots report their location to a computer and displays them on the software. The iRobot vacuum cleaners eat up the paper. The Roomba Pac Man experiment was designed to demo an Unmanned Aerial System software suite.
