The Nerd at Playcrafters Barn Theatre Through September 25

As the lights come up on Playcrafters' production of Larry Shue's The Nerd, we find ourselves in the Terre Haute, Indiana, living room of architect Willum Cubbert (Josh Kahn), whose pseudo-girlfriend, Tansy (Jessica Nicol), and drama-critic friend, Axel (Chris White), are throwing him a surprise birthday party. For about 20 minutes, the three characters chat, and all the while, the light from the evening sky - seen through Willum's living-room windows in the rear of the stage - is going through the most amazing transformation. The reddish-pink hues from outside begin to subtly shift to a lovely magenta, and within time, they will have morphed into a deep, midnight blue with a hint of purple; it's a beautiful, subtle effect, well-achieved by designer Jennifer Kingry.
