For TED’s 30th anniversary, artists Janet Echelman and Aaron Koblin collaborated to create Unnumbered Sparks, a monumental interactive sculpture in the sky. Choreographed by visitors in real time through their mobile devices, at night the sculpture became a crowd-controlled visual artwork on a giant, floating canvas.
The sculpture spanned 745 feet between buildings in downtown Vancouver, Canada from March 15-22, 2014. At night, it came alive with illumination. Visitors with smartphones and tablets were able to paint vibrant beams of light across the sculpture at a remarkable scale: small movements on their phones became hundred foot long trails evolving and combining with fellow participants.
