Aquarium Uses Eel Powered Christmas Lights 96
A Japanese aquarium is using the greenest energy possible to power the lights on its Christmas tree, an electric eel. From the article: "Each time the eel moves, two aluminum panels gather enough electricity to light up the 2-meter (6 ft 6 in) tall tree, decked out in white, in glowing intermittent flashes."

... so if the eel is in sight of the tree, and is photophobic (or -philic), can one set up an oscillation in which eel movement causes light which causes more movement, making the tree lights flash at a substantially constant rate?
