Make Weekend Projects – a touchless 3D tracking interface

[Video Link] This Weekend Project from MAKE is really cool: a touchless 3D tracking interface made from foil and cardboard.

Using a combination of low- and high-tech components, we'll show you how to build a completely touchless 3D tracking interface. This project will introduce you to the principle of capacitive sensing, and the Arduino microcontroller.
