To demonstrate:
This is a module called Stochaos designed by Andrew Fitch (nonlinearcircuits.com), based on a 1980 US Patent.
Here it's driving two envelope generators, which are controlling two voltage controlled amplifiers, each being fed different kinds of noise.
(yes I can see all the dust. yes there's a bit of tape covering the LEDs, its because I didn't select the right value of resistors and they're too bright. Yes one of the LEDs is duff)
