Full Detail about this project : dscript.org/rainy-day-diy-music-laser
I like to call this one the "rainy Day" because the second mask reminds me of raindrops.

The System has several elements...
1.The laser is hung from a speaker so that the vibrations cause the laser to "bounce up and down' in resonance with the music.
2.Water is sprayed onto the primary mirror from a nozzle that is shaken by another speaker.
3.The primary mirror is slanted heavily vertical, so that water hits and slides of quicly, creating a "very reactive" primary mask.
4.The beam bounce off the primary mirror onto the secondary mirror which is showered in droplets falling from above.

Off the secondary mirror and project straight on to the wall.

The system leaves many areas that can be improved. ones I plan to address first are...
-increase laser bouncing
-increase jet vibration
(both of these just need bigger speakers)
-add water pump instead of water tower
-scale down as much as possible without losing the range of effects.
