For a region so recently addled by an electricity-snuffing derecho, an exhibit titled “Atmospheric Front” sounds positively ominous. Fortunately, the installation at Flashpoint isn’t so off-putting, though it also doesn’t quite live up to its potential. Two sisters, Hana Kim and Shana Kim, had the idea of suspending cotton twine from the ceiling using wires attached to a series of pulleys and motion sensors, so that the web-like forms would shift and morph whenever a visitor walked by. It’s an inspired idea that smartly mixes technology and craft, but project’s sometimes balky mechanics and the work’s limited degree of shape-shifting fall short of what other moving installations have accomplished at Flashpoint, notably Janell Olah’s translucent plastic ducts, which inflated whenever air rushed through the gallery’s HVAC system. Of the three hand-knit pieces that make up the Kims’ installation, two hew closely to a hammock shape, with netting that doesn’t look nearly sturdy enough to support the average body. A more intriguing shape is the third, which is flatter and tilted at a steeper angle, almost like a vertical slice; this portion of the work allows a viewer to imagine that a load of contents has just been dumped all over the ground.
