I have accomplished with laser show program for mac(is also possible with a frequency generator program)and music cool effects.
The vibrations from the 2 base speakers (with 1 mirror an each speaker) makes the laserbeam move with the music and the frequencies (audio).
Step 1: What you need
2x base speaker
2x mirrores (1,5cm X 1,5cm)
an borde (wood)
2x plastic pices(1mm thick)
wooden stix (p.ex. "mikado stix")
