Bathroomgoer

The exhibition lasted only from 6 to 6:26 p.m., the artists said, because a security guard, alerted by concerned bathroomgoers, showed up and tapped on Mr. Hartshorn’s shower curtain.

We were not about to be accused of peeping through a hole in the wall—every bathroomgoer was now in charge of their own peeping. Lots of cool pictures came out of that.
