"Janet Echelman found her true voice as an artist when her paints went missing -- which forced her to look to an unorthodox new art material. Now she makes billowing, flowing, building-sized sculpture with a surprisingly geeky edge. A transporting 10 minutes of pure creativity. American artist Janet Echelman reshapes urban airspace with monumental, fluidly moving sculpture that responds to environmental forces including wind, water, and sunlight." from http://www.ted.com/talks/janet_echelman.html
