Anyone passing by the Advanced Health Sciences Pavilion on Cedars-Sinai's main campus is sure to notice and appreciate artist Robert Irwin's dramatic light creation. A year in the making, the dramatic configuration of fluorescent tubes in the building's northern exterior shines day and night and never looks the same.

The building's wall of windows wraps around two sides of a triangular area located where Gracie Allen Drive meets San Vicente Boulevard. Known as "the prow," it's a space that the building's architects intentionally left empty, says John T. Lange, the curator of Cedars-Sinai's art collection. "The prow is a space no one will actually go into, other than for maintenance. The architects approached us with the idea of doing something wonderful there with art."

Artist Robert Irwin, who began his long career as a painter, was inspired by the space to create a grid of lights, 124 slim white tubes bent at right angles. The tubes cover the rear wall with a web of light and shadow that, despite the size of the installation, never repeats.

Irwin calls his artwork a "conditional response" to the narrow, angular space it occupies.
