A three-story fluorescent light installation by Robert Irwin entitled Light and Space III was specifically designed for the Museum's main 60-foot atrium Pulliam Great Hall. Unveiled as a commission in honor of the Indianapolis Museum of Art’s 125th anniversary this October, the work is the IMA's newest and largest addition to its fast-growing contemporary art program.

Light and Space III transforms the experience of entering the Museum's galleries with a 60x60-foot screen stretching across three adjacent planes by the main escalators. A series of white floor-to-ceiling scrim panels brackets five channels of fluorescent light mounted in a grid-like pattern across the wall surfaces. Visitors are blanketed by a tunnel of light as they move between the three gallery levels of the IMA. The commission is funded in part through a gift from Ann M. and Chris Stack, longtime supporters of the IMA's contemporary collection.
