Lisa Hein and Robert Seng have installed a new site-specific light animation, CALENDAR, in the GRIDSPACE storefront in northern Crown Heights, Brooklyn. Between dusk and midnight daily, the storefront’s 12 cubbyhole-like compartments illuminate one by one in a short loop, symbolizing the passing of a year (one light square per month). A second, independent loop activates a flurry of multicolored “holiday” lights, which the artists explain, “strike at any season.” In a neighborhood with many storefront churches, the piece functions as a stained glass window for the modern city. A closing reception will take place at GRIDSPACE on Sunday, February 13 from 5 to 7 p.m.
