I knit clear plastic tubing into sculptures and clothing. Air and colored fluids are pumped through the tubing to produce color-changing, pulsating, dynamic textiles. An Arduino microcontroller controls solenoid valves which create patterns with the various fluids while pumps and compressed air propel them.
I am a mechanical engineer by training, informal educator by profession, and very hack fiber artist by night. I had experimented with tubing and colored fluid sculpture several years ago, but I didn't feel compelled to follow up on it until visiting the Maker Faire last year.
