This aerial sculpture is designed by Janet Echelman for the TED 2014 (Technology,Entertainment and Design) Conference. The 745-foot wide installation is made of soft netting, and suspends between the roof of the Fairmont Waterfront Hotel and the Vancouver Convention Centre. Viewers can control the lighting of the piece with their cellphones.
Janet Echelman said that this artwork, titled "Skies Painted With Unnumbered Sparks," is “like a custom-knitted sweater for the city.”
