Wait, you did name your guppy Dory, right? Whatever your household fish is named, you can certainly give it a fresh purpose in life with the RhythmFish -- if it were more than a mere concept, of course. The setup surrounds your fish with webcams and monitors its movements via sensors in order to translate all of that data and put forth a visual interpretation. In all honestly, it's probably just some sort of randomizer hooked up to a Windows 95 screen saver, but a boy can dream, can't he?
