I'm often impressed upon my first glance at the set when I enter the Black Box Theatre: the opulent, creepy one of The Turn of the Screw; the enigmatic jumble of portraits and ripped flags for Assassins; the varying, multiple-locale settings for Little Women: The Musical. (This venue's crews find the most wonderful furniture and set dressing, too.) However, the set for playwright Lauren Gunderson's Natural Shocks, the Black Box's current production, blows them all away. I think I actually froze in astonishment.
