[sdiy] Nice Noise Source

Hey Charles, it looks like Moog beat you to it (at least for today):

MF-FM: NEW MOOGERFOOGER EFFECT USES BROADCAST RADIO SIGNALS

The MF/FM has an on-board analog radio tuner, capable of locking into
frequencies across the FM radio band. Mix any instrument with live
radio signals, and tweak the voltage controlled oscillator for
modulated madness and creativity

Its available April First.. nice :)
