Time Out says
'White Bouncy Castle' is a choreographic space that's the brainchild of the great American choreographer William Forsythe, in collaboration with performance artist Dana Caspersen and composer Joel Ryan. There are no performers other than you, the public, and all you have to do is enter the giant cube that's in the form of a big white inflatable castle, and jump, dance, and bounce around. Fall and get up again, getting a feeling of instability in your body, and awareness of all your movements, all to the soundtrack of a composition by Ryan. Take it seriously or enjoy the absurdity of it all, including the almost addictive feelings and sensations it provokes.
