Friday

"O Stone Be Not So." Now that simple robotics technology is affordable and available for the home market, a slew of artists and experimental makers have been able to tinker like never before. A group exhibit of up-and-comers from around the country — Andy Holtin, Jenny LeBlanc, Troy Stanley, Gregory Witt and Katie Wynne — features new kinetic sculpture and kinetic installations. Buzzing, whirring, moving — this art doesn’t just delight in the technology, but also questions the shifting culture that now surrounds our technological society. Opening: 7:30 p.m. to 11 p.m. Friday. Exhibit continues through April 5. Gallery hours: 5 to 8 p.m. Fridays, noon to 5 p.m. Saturdays and Sundays. Mass Gallery, 507 Calles St. Free. www.massgallery.org.
