Cheesy Laser Beams Video

Many different laser beam music systems exist. The concept is simple: Break the beam and the beam’s corresponding sound is played. Musical laser systems can vary widely from performance-grade monstrosities to cheesy, plastic, consumer models like this one from The Sharper Image. Watch the video, point and laugh:

I just don’t know if this is a viable musical instrument. The guy rocking out with the sunglasses isn’t even playing to the beat, yet the music comes out perfectly. It seems to me that no matter how you play the instrument, you will always be in perfect time because each beam’s recording is always in sync with the rest. Not very creative.
