I created this image using a projector (and screen), a Wii controller (as a camera), the FriiSpray IR Can (which is a cool MTN 94 can with an IR led cap), Smoothboard Wii whiteboard program (tracks the IR beam from the FriiSpray), and Painter (because I like to try different “paints”, and having layers is real nice too).
It’s pretty cool to “doodle” on such a large scale and try stuff out without the risk of ruining a huge ($$$) canvas just to discover that your idea is not so great after all. Just hit delete, and start again!
