Lukas sent me this link to the Runaway Harp by Tracy Tsang. Each column of water has an LED at one end and a sensor at the other. When the user interrupts the stream of water, it triggers a sound created by the Arduino. Very cool! [Thanks Lukas]
The idea of Runaway Harp came from the thinking that an instrument can have her own personality also and therefore wish to express herself in another form. The use of circulating water coincides with our original idea of using Time as a topic for our project, while the actual water interaction was decided from experimentations with water projections.
