An aerial canvas
Unnumbered Sparks was a large, interactive sculpture installation on display at the 30th anniversary of the TED conference in Vancouver, Canada, during March 2014.
The sculpture, a net-like canvas 745 feet long and suspended between downtown buildings, was created by artist Janet Echelman. Aaron Koblin Creative Director of Google's Data Arts Team created the digital component, which allowed visitors to collaboratively project abstract shapes and colors onto the sculpture using a mobile app.
Projection mapping technology translated their actions onto the correct location of the shifting fibers in real-time.
