By accident i found something weird today...
I was experimenting with CD4093 gate-able oscillators. When the input is not connected/grounded it get's unstable, i did leave the breadboard wire there, and accidentally i touched one ear of the pot, and suddenly the circuit became a like a theremin, with the wire acting as an antenna! It still is very unstable and i have no idea how it works...

(see attachment for circuit)

hmmm, interesting. i built it, and yes indeed, it is quite unstable. toward the end, i couldn't get the same kind of sounds i did when i first turned it on. might be handy one day for something.
