We did a similar project @ PICNIC in 2009 building this networked Etch-A-Sketch called ik-a-sketch – see http://www.mediamatic.net/page/110257/en This project ended up swamping PICNIC conference attendees’ profiles with scribbles… We used a shortrange projector, two potentiometers, arduino and processing. The clever bit was an accelerometer in the frame, so people could erase their drawings by shaking the massive board – or by jumping in front of it….
