Rather than using a lens, which would be difficult to obtain, even using ebay, could one achieve the same effect by scanning the laser dot in a line using a rapidly spinning mirror? I believe one of Baird's mechanical TV cameras used a system a bit like this, with the upshot that the performer had a faceful of intense, spinning light patterns all the time! Perhaps several camera frames could be averaged if the brightness decreased too much.
Cool! Now if I can just restrain myself from trying to build one and get some of the other things I've started finished.
