I really enjoy large-scale robotic sculptures like Sixteen Birds. The website has a lot more information about the piece, including fabrication details and a nice video.
Sixteen Birds is the first multi-sculpture installation using Amorphic Robot Works’ (ARW’s) new Inflatable Bodies technology. The work consists of 16 large, white fabric shapes that recall the simplest line drawing of a bird, hanging limp and lifeless from the ceiling at eye level.
