Always wondered how they do it in that ‘Talk, Talk, Talk’ ad where people sort of draw on the TV screen and it makes some sort light marks – ‘light painting’ that is.

ART-PIE will eat it soon if he can get a camera and people to help as the basic idea behind light painting involves holding the shutter open on a camera for a period of time while someone waves a light source in from of the lenses.
