      I shine it through a fibre optic to make a pretty pattern, and then I use the light that’s reflected back up the fibre to work out what the scene at the other end looks like. I’m basically just using it the way you use a lightbulb when it gets dark, but because the beam is narrow I can fit it down a fibre optic.
