Though these moving pendulums look like a booby trap from an action movie, they are actually part of a “choreographic object” designed by William Forsythe. The hanging plumbobs rhythmically swing back and forth, making visitors interact with and dance through the web. The hundred-part installation, named “Nowhere and Everywhere at the Same Time No. 2,” can be found at Circus Street Market through May 25, 2014.  Free and open to the public, “Nowhere and Everywhere…” is part of the annual Brighton Festival in England.
