Here are some more images from the construction of the project I made for Interactive and Multimedia Art. I used this 1/8" x 3/4" copper stock to make the "buttons" for the project. They are all wired up to an Arduino. I ended up running a ground plane of steel just below each copper strip too. I built a foam stand for the TV to rest on.
Touchy-Feely Lamp (just like my compact!)
