In case anyone is in any doubt as to the danger of lasers, or the fragility of camera and projector sensors, take a look at these...
That happened at ~25m range, using max 3.5W RGB laser and thats a very knackered £2.5k LCD part!
What I find interesting is the concentration of damage down the very sides of the large image. I wonder if the nature of the projector lens working as a reverse telescope causes beams to concentrate more in these areas when they enter the lens on the periphery.
