An interactive, kaleidoscopic touch-screen light wall created by Philips Electronics, Andover, Mass in a hospital maternity ward helps distract the captive waiting room occupants in its midst.

The Imagination light canvas in the women’s and children’s waiting area at Mercy Medical Center, Rogers, Ark—which opened its doors this month—measures 14-feet-long by 6-feet-high, and relies on the company’s technologies to animate some 1,420 LED lights.

Touching their hands to the wall, visitors paint with light in a full spectrum of colors and shapes. Images disappear after a few minutes. Six people can participate simultaneously, yet the display consumes the daily energy equivalent of just one toaster.

The company’s employees donated the wall, which helps reduce stresses that often grip families waiting for the birth of a child.
