Festival fills Tokyo river with firefly-like delights5/14/2012
Tokyo's Sumida river isn't being overrun by electric eels. It just looks that way in this incredible photograph, part of a waterborne art project designed to look like fireflies meandering throughout the colossal city, for its Hotaru festival. One hundred thousand blue solar-powered LEDs were dropped into the water and extensively photographed as they floated along by moonlight, and were eventually collected with giant nets. Solar powered at night? That's what they say, and who are we to argue? "Hotaru" is the word for "firefly," but from now on we'll always associate it with simple, modern magic. It's poetic.
