Inflatable sculptures, May 28-31 at Houston's Discovery Green park. The show, Light as Air, features Susan Robb's giant toobs, Sharon Engelstein's animal conglomerates, David Graeve's photobubbles, and Pat Oleszko's Footloose and Fantasy Free and begins at 6am on Thursday. At 5:30 that evening, Robb, Engelstein and Graeve will be on hand to talk about their works, and on Saturday, May 31 at 2pm Robb will lead a hands-on kite making workshop, transforming garbage bags into flying bugs. (Doesn't that happen naturally?). Free!
