“Water Music”, anyone?

YouTube video posted by LittleScale, who also provided this explanation at the sidebar:

A slightly more complex version of using a water surface as a music controller featuring five lasers instead of just the one. Please note that this is a prototype version, and as such does not represent the variety of output for the finished thing.

Here’s his earlier setup, which is equally instructional.

A cheapo laser pointer, a solar panel and a clear vase filled with water are transformed into a music controller. Includes demonstrations of amp modulation, amp and freq mod and a more complex mapping as well.
