To celebrate its 125th anniversary, the Indianapolis Museum of Art (IMA) commissioned artist Robert Irwin to create a light display for the Pulliam Great Hall which would transform the experience of entering the Museum galleries. Installed on the walls surrounding the escalators, Irwin's Light and Space III is an arrangement of fluorescent light bulbs in an irregular grid pattern, which creates a feeling of both randomness and uniformity at the same time. Framing the sides of the escalators are stretched fabric screens which have the effect of filtering the light. To match the angle and depth of the escalators, a partition wall was hung from the ceiling. Lights mounted on this wall add depth to the display. Silver Creek Engineering designed the wood stud partition wall and its support, as well as the support for the stretched fabric screen wall. The entire display was created at a cost of one million dollars and occupies an area of 3600 vertical square feet.
