In the middle of Chelsea’s bustling Pace Gallery, it comes as a surprise to hear your own heartbeat filling the cavernous room housing Rafael Lozano-Hemmer’s interactive installation ‘Pulse Topology.’ Placing your hand under one of three small monitor suspended from the ceiling not only broadcasts the sound of your heartbeat but translates it into flashing lights in one of thousands of lightbulbs suspended in an undulating pattern from the ceiling. Though essential to life, we often take our beating hearts for granted; making them the focus of an artwork not only flips interior functions to the exterior, it speaks to something visitors have in common. (On view in Chelsea through Oct 22nd).
