This is the 1.26 Sculpture Project, that was installed in Sydney, Australia in 2011. It's just one of the many beautiful net sculptures created by Janet Echelman. Her next project will be twice the size of her previous largest, suspended 745 feet between a 24-story skyscraper and the Vancouver Convention Center. The goal is for it to be erected in conjunction with TED's 30th anniversary later this month.
Echelman initially planned to be a more traditional artist, going to India on a Fulbright lectureship. But when her painting supplies failed to meet her there, and bronze proved to be too expensive on her budget, she became inspired by the nets she saw local fisherman using. Since then, she's installed numerous net sculptures all over the world, which you can see on her website. Below are a bunch of photos from the 2009 work "Her Secret Is Patience," in Phoeniz, AZ and a time-lapse video showing it go up.
