Wonderful things happen when artist and coders collaborate, nuff respect to the City of Vancouver for curating this awesome project.
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 (map). 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.
