Graffit!

Virtual spray painting with Max and Jitter. We used  a cheap webcam hacked to see only IR light,  then used it with a cool IR spraycan from Friispray to give the effect of virtual graffiti. Users could change the colour of the 'spray' with switches along the bottom of the spraying surface.  As well as the spray can, a fishing rod style tool was produced to enable spraying from a distance.
