Speaking of FFTs, in my quest for more "squiggly lines"
I am playing with an electroencephalograph (EEG) that was 
designed in the same spirit as Larry's quake system. The 
specs are public and anyone can build it, or a complete 
system can be purchased. Interestingly, most of the tech
concepts are the same including A/D conversion and FFT.
But obviously that data interpretation is a completely
different story. The EEG uses electrodes on my scalp to
listen for different brain wave activity in the delta,
theta, alpha, and beta ranges. Check it out: and
