The TED conference was hosted in Vancouver this year for its 30th anniversary. Artist Janet Echelman collaborated with Aaron Koblin to bring an amazing piece of work to the city called "Unnumbered Sparks" specifically for the conference.
Unnumbered Sparks is a 745 foot interactive art display that can be controlled through your mobile device to see beautiful sparks in the sky.
During the day it appears to look like a massive net in the sky.
As the sky gets darker, is when the colours really start to show
I hope you enjoyed the time lapse video and the photos. For more information on the art display visit http://www.unnumberedsparks.com
