Influence

My idea is to make something like the Interactive Coffee Table by the Evil Mad Scientist Laboratories have made.

The designers have used a coffee table and added hundreds of LEDs on the top surface of the table. The LEDs responds to any movement above the table.

I believe all my ideas are going to revolve around sensors. Sensors of activity, heat etc. The sensors may lead to music, light or movement.
