It's a little odd to create such a heavily digitized critical look at the digital age, especially when what draws you in isn't the technology: what works best in this collaboration between the Builders Association, a performance group, and dbox, a multimedia studio, is its human aspect. Of the three story lines, delivered in interwoven vignettes featuring live and projected performances, two have genuine dramatic interest. In one, a Ugandan businessman has successive encounters with U.S. immigration agents who know more and more about his life--sometimes things he doesn't. The agents are all cleverly differentiated, and the businessman's burgeoning frustration and stress are both humorous and terrifying. In the other good story, an increasingly forgetful but charming Sri Lankan grandmother communicates with her granddaughter in New York by computer videophone. Their funny, affectionate exchanges make you really regret the elder woman's loss to senility, a change that seems tied to the images and information that inundate her. The third story, in which a middle-class father tinkers with his son's identity, is about as interesting as a Sims family being moved around its digital home. a Thu 10/12-Sat 10/14, 7:30 PM, Museum of Contemporary Art, theater, 220 E.
