The original Arduino project started out as a program for developing a device for controlling student-built interaction design projects, albeit at a much less cost than other comparable prototype mechanisms. And now after 5 years, and more than 120,000 Arduino boards being sold, modders still find ingenious ways to utilize this open source single board micro-controller. In the latest of the fascinating DIY contraptions, folks over at AdnanOnline (Adnan AlHomsi and Koussay Daadoush) created a remote controlled car that can be maneuvered by the Xbox 360 Kinect which in turn uses the convenient Arduino system.

The Kinect acts as the motion sensing input device, which feeds the digitalized info to the Arduino controller. Thus, according to the movement of the user, the motion of the toy car can be regulated. The whole controlling attribute is certainly a little bit 'rough around the edges' (judging from the video); but the idea of maneuvering a toy car by just the movement of your body is intriguingly novel in itself.
Deciphering the practicality of the overall application is left to you, and while doing that, you can always check out the cool video.
