This is an early test of our Capacitive Tree, it senses your hand up to 4 inches away and visualizes it on screen.
The tree is painted with conductive and non conductive paint, then wired through the bottom with a bolt connect to an Arduino, which sends its sensor readings via serial to Processing for a little visualization.
The visualization was made from a photo of the table that was thresholded and output as a png with the black cut out. Then Processing simply takes the output from the Arduino and draw circles that grow as it sense a hand getting closer.

Hmm…it looks like things are taking a while to load. Try again?
