I need basically what you see in the movies, where people are somersaulting around around the lasers. Break contact of a laser, and and an alarm is triggered. I've been having miserable luck googling, maybe I just don't know the right words. Preferably cheap, not terribly afraid to build from components.
Any thoughts?
