This instructable will show you how to make LEDs light up at your finger tips upon contact with a flat surface. You may choose to sew the components onto a glove to make an LED glove.
The main reason for this project is to interface it with a multitouch table setup without going through the hassle of setting up an Infrared light pane. (See NUI group
for more information.) Essentially, to get a finger recognition software to detect the LED lights as fingertip inputs.
you can just build it for fun :)
