Made from two thrown away hard disks. Just mounted two mirrors on the actuator arms and gave an audio output from an amplifier directly to them. The laser is from a cheap laser pointer I bought from a store.
Interesting thing is that it generates the exact sound wave given to it just like an oscilloscope.
