Tiny figures perform enormous undertakings in delightfully absurd new sculpture and 2-D works by Liliana Porter at Bienvenu, Steinberg and J in Tribeca. Miniscule men with leaf blowers raise up a storm of swirling forms while a little woman with an even smaller a basket of glitter spreads the shiny material into an expanding field of brightness. Ruptures in scale and contrasts between the real and represented are the stock in trade of Porter’s six decades of artmaking. Here, magical scenarios convert mundane acts by individuals into aesthetic gestures for the public. (On view through Oct 14th).
