Theatre Review: "An Ark" and "Data"

Two plays soaked in technological anxiety. "An Ark" resembles a webinar with a staring contest, one that no human can win. Before you enter "An Ark," a "mixed reality" performance at the Shed, you check your coat and, more oddly, your shoes. Inside, there are three concentric circles of chairs arranged on a red carpet and, overhead, a white globe resembling a hot-air balloon. A docent explained that, through my virtual-reality headset, I would see four more chairs--and, ideally, they shouldn't float.
