I was clicking around youtube, about a month ago and just decided to post this today, Anyways when I came across this I thought it would be a bit of amusement for you guys. Enjoy!
From what I under stand is its a digital video camera connected to a pc, which scans the target screen and traces the laser and then it feeds the display through a projector, some s bound to provide a better explanation or at least a link to a better one but I don't care I just thought this was cool techy stuff!

Certainly is an interesting idea, although I think it could be put to a lot better use in an office environment. Maybe something like using a laser that has a red dot so the user can see it, as well as a IR one that a camera (with at least a visible blocking filter, preferably a nice tight bandpass filter at the ir wavelength) and superimpose the graffiti image with the presentation such that the presenter could draw little sketches and whatnot.
