Members of the Manchester, UK hakcerspace HAC:Manchester used a projector, an Arduino, and some rotary encoders to build this giant project-a-sketch. Here’s a video of it in use by Maria of

    Neet, but could the video been any more annoying?

    Cool! We did a similar project @ PICNIC in 2009 building this networked Etch-A-Sketch called ik-a-sketch – see 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….
