Walking into work this morning, I thought I saw David Blaine sitting atop a pole outside the Nasher, on Flora Street. Long a fan of the lost art of pole sitting, I was prepared to bring a chair and a couple beers back from the office so I could set up shop and watch the spectacle. Upon closer inspection, though, I saw that the figure atop the pole (there are actually two, one at either end of the Nasher’s facade) is part of Jaume Plensa‘s “Genus and Species” show. No rush, then. The show opens January 30.
