So, it's not exactly clear what a 'Cyborg Biolab Biofeedback Rack' (eBay item #7563183120) is, but it certainly looks the part. "This unit is a full-on audio biofeedback instrument. you could 'play' it with your biorhythms. You could use it as an 'audio lie detector'. You could let it hang out and be cool and beep and stuff" It also has 'Cyborg Corporation' written on it. No bids yet for the $20 starting price. (Thanks Russ)
