Two major shows currently on view in NYC are Richard Serra's Junction/Cycle at Gagosian Gallery in Chelsea and Carsten Höller's Experience at New Museum. Though totally different in execution, both invite viewers' active participation by physically travelling through the installations - leisurely walking in Serra's while recklessly dashing in Höller's.
Serra at Chelsea's Gagosian, New York 2011:
The Serra experience is contemplative and personal, almost like a pilgrimage. One couldn't help feeling enlightened while exiting. Höller's Experience, on the other hand, is more sensory and spontaneous. It is a re-interpretation of his 2006 Unilever Series project at Tate Modern in London. I must confess that I actually did not experience Höller's installation first-hand. Deterred by the long queue waiting to get in, I decided to observe from a distance instead. Here's a glimpse of what it looks like:
