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.
