[sdiy] Don't Touch

[John L Marshall]

The Korg thread start me thinking, again (I know, dangerous).

How many ways are there to control an analog synthesizer without touching?

1. Electrostatic detuning (Theremin)
2. Electromagnetic detuning (with a magnetic ring on a finger)
3. Ultrasonic reflection
4. Infrared reflection
5. Optical reflection
6. Optical interruption
7. Infrared interruption
8. Ultrasonic interruption
9. Light pen and photocell targets
10. Wand with accelerometer
11. Video camera and a powerful computer


Feel free to add to the list.
