The Toriton is an instrument based off of work done by Sebastian Tomczak.  In my version, calm music is playing in a room.  Three bowls sit on a table in the center amidst other glasses and stones.  When the water is disturbed, the audio playing is disturbed in a similar fashion. The device works through the use of a laser pointer hanging above each bowl.  The laser shines through the bowl and on to a photoresistor.  When the water is disturbed, the laser is deflected off of the sensor.  I read the sensor values into my computer using a microcontroller.  Once in the computer, I could use those value to modulate the playing music using any variety of effects.
