Citing Alexander Calder’s mobiles and Felix Gonzalez-Torres’ beaded sculptures as touch-points, Jean-Michel Othoniel presents ‘black tornados’ at Perrotin on the Lower East Side. Made of aluminium beads threaded onto a steel armature, the glittering twisters reflect light and suggest movement while presenting natural phenomenon as glamorous ornament. (On view on the Lower East Side through April 15th).
