"Radio interference, traditionally a problem in audio, can be used to our advantage. By means of the Thereglyph instrument I would like to introduce to circuit-bending a concept I call radiopool.
While Leon's Theremin looks to onboard RF generation and sounds the same played anywhere, immersing a radiopool instrument to various depths within the RF field (the radiopool) yields changing results... similar to differing the length of the air column within a flute.
Here I'm playing the Thereglyph within the radiopool of a plasma globe - sometimes touched, sometimes not. For more info on this instrument and building one yourself, check-out my flickr gallery:

"Thereglyph With Plasma GlobeTo radio-fy a bent instrument, first try to create an unstable audio circuit.
Benders are familiar with a potentiometer setting that places the circuit at the edge of crash. In this precarious configuration the circuit is very susceptible to interference.
Begin experimenting with RF generators nearby the circuit - a small plasma ball is a strong, but dirty, RF source. Move the ball. Place your hands between the circuit and the RF source. Experiment with adding antennae and metal plates to circuit points. Touch or wave hands nearby these extensions!"
