Toriton Plus, a water surface music controller being played live.

By using a voltage divider for each laser, the physical interface can see changes in voltage
This is what you need:
A solar panel (2V to be able to connect it to the audio in port on my MacBook), $10 Some cabling (a 3.5 mm standard stereo plug) A bowl of water A software synthesizer that can read input from the audio in port.
