I am not sure what the thing is actually called, but let me see if I can describe it. It is one of those products advertised on tv, that you put on a wall and it shoots a laser beam all along the surface parallel with the ground.
The problem I can't figure out is, some of them claim it can go around corners (i.e. around a corner onto a wall the device can't even see directly).
It seems like this should be impossible to me, and I can't figure out how it would work. Anyone have any idea?
