Brooklyn is oh so hip, it’s even the location of a new play that just opened at the Public Theater starring Sandra Oh (of Sideways and Gray’s Anatomy) called "Satellites." Garnering great reviews, the appearance of this new play demonstrates that that Brooklyn is more than just a place but a state of mind or at least the zeitgeist of the moment.

This house will not stay still. Floorboards might as well be skateboards in the old Brooklyn brownstone that is the setting for "Satellites," the tough-minded, softhearted and very likable new play by Diana Son that opened last night at the Public Theater

Thanks to the ingenuity of the set designer Mark Wendland, rooms slide sideways, backward and forward in this study of big-city identity crises from the author of "Stop Kiss." A seemingly solid structure splits again and again into a house divided, as distinctions between outdoors and indoors, between public and private, melt and dissolve. For Nina (Sandra Oh) and Miles (Kevin Carroll), a couple who have just moved from Manhattan with their newborn daughter, home has all the stability of a runaway taxi.

Urban flux indeed. The kinetic set for "Satellites" isn’t just the latest example of a designer strutting his virtuosity. Ms. Son is examining a world in which traditional ethnic, social, economic and sexual boundaries have become so porous that people are never quite sure who or where they are at any given moment. It feels absolutely right that the ground should shift so literally beneath the feet of Ms. Son’s wandering, wondering characters.
