Here's the Bamboo Exhibit on the Roof of the Met

Says the Met website:

Invited by The Metropolitan Museum of Art to create a site-specific installation for The Iris and B. Gerald Cantor Roof Garden, the twin brothers Mike and Doug Starn (born in New Jersey in 1961) will present their new work, Big Bambú: You Can't, You Don't, and You Won't Stop, opening on April 27. The monumental bamboo structure, ultimately measuring 100 feet long, 50 feet wide, and 50 feet high, will take the form of a cresting wave that bridges realms of sculpture, architecture, and performance. Visitors will witness the continuing creation and evolving incarnations of Big Bambú as it is constructed throughout the spring, summer, and fall by the artists and a team of rock climbers. Set against Central Park and its urban backdrop, Big Bambú will suggest the complexity and energy of an ever-changing living organism. It will be the thirteenth-consecutive single-artist installation on the Roof Garden.
