"Flight Over Sahara" is MotioGames first web-based webcam game that allows you to fly around the desert by moving around in a little window and making shooting noises with your mouth... or other orifice. Cool little bit of programming. Since our iSight is out of the country right now, we couldn't play this game and kept hitting pyramids, but let us know how far you get. Also, turn down your speakers because the intro can get annoying.
