Remember the Big Mouth Billy Bass? You’d press a button (or trigger a proximity sensor for a surprise) and the fish would start singing either Al Greens Take Me To The River, or Bobby McFerrins Don’t Worry, Be Happy. 

Texan Richard Carter took a Volvo, 5 miles of wire, five 6-volt golf cart batteries, a screw drive mechanism using 12v DC reversible motor, a lifting frame he made from scratch, a Linux server and approximately two hundred synchronized singing fish, and created what can only be described as an awesomely effective assault on good taste: the Sashimi Tabernacle Choir.
