100,000 LED Spheres Flowing Down a Japanese River

As part of the recent Tokyo Hotaru Festival, 100,000 illuminated blue LEDs were released in the Sumida River. The massive installation of solar-powered spheres was meant to mimic a swarm of fireflies that twisted and bobbed along the river by moonlight. For those of you worried about pollution or safety, the lights were later caught downstream by giant nets. See much more over at Spoon & Tamago.
