"Sponge material shows an extremely large dielectric constant that changes with the amount of compression. It can be made into a wide range variable capacitor when clamped between two metal plates. Capacitors in the range of 100nF can be made with only a few cm of (cellulose based) sponge material.
This movie shows a sponge-based oscillator and a sponge-based lowpass filter as an introduction into 'Spongetronics'. Comes with oscilloscope waveforms and resulting sounds. More info on Elektor Labs."
We've had shoe gazing, and then generative. Next we will have squarepants music.
