Fun with Lazorz

I discovered a fun puzzle thanks to puzzlinks.com: http://www.gamingdelight.com/games/laserlogic.php

Each round has a grid with some lasers and targets of various colors, and you have some mirrors, prisms, and filters at your disposal. The goal is to hit each target with the right color(s) of light. I'm currently on puzzle 16, and it's starting to get very interesting. Highly recommended!
