Janet Echelman creates interactive artworks that are breathtaking and inspiring, watch the TED talk by Janet Echelman: Taking imagination seriously.

Excerpt from Ted Blog:

These were some of the comments heard at TED2014 about Skies Painted with Unnumbered Sparks, a collaboration between sculptor Janet Echelman and data artist Aaron Koblin. This monumental sculpture stretched 745 feet, from the Vancouver Convention Centre where TED was held, over an open-air plaza on the edge of Vancouver Harbor and up to the top of the Fairmont Waterfront hotel. Every night while the temporary sculpture was installed, from March 15-22, 2014, dozens of people could be seen across the street setting up cameras and tripods to capture the glowing spectacle. Meanwhile, underneath the sculpture, even greater numbers of people gathered, most of them with their phones out. Using a phone, they could draw lines, squiggles, webs, and water drop rings onto the sculpture’s lush purples, blues, pinks and oranges.

Aaron Koblin: Visualizing ourselves … with crowd-sourced dataAaron Koblin: Visualizing ourselves … with crowd-sourced dataKoblin, of Google’s Data Arts Team, told us a little about how it worked.

“The lighting on the sculpture is actually a giant website,” Koblin says. “It’s one huge Google Chrome window spread across five HD projectors. The content is being rendered in WebGL. It uses Javascript and shaders to render particles and sprites based on user motion, which is transmitted from mobile browser to our rendering browser via websockets. There are a lot of moving pieces here, from the local area network to the server (written in Go), to the sound system (also running in Chrome with Web Audio API) all the way through the LED light control system, which pulls pixel data directly from the browser.”
