At most art exhibits, guests aren't supposed to touch the works – though the current exhibit at Discover Portsmouth is the exception to that rule. In fact, some of the pieces won't work unless you touch them.
It's an exhibit called “In Motion,” and the artist, Kim Bernard, joins All Things Considered host Brady Carlson to talk about exploring movement through visual art.
