Laser knowledge

Maybe a mechanism to throw £1500 on the floor in front of you would work.

How frustrating would that be if you had a gait freezing episode

More seriously, would just a simple laser pointer or even a powerful led mini torch work?. Would a spot trigger the same response as a line?

Line seems to work ok. I cant see how a spot would help.
