Two, parallel,  single-glazed, 504 Rough Cast channel glass walls wrap the staircase of the university’s recreation center. The resulting curved, double-glazed channel glass wall, set in the I-41 frame system, encloses a color-changing LED lighting system. The programmable LEDs allows combinations of colors to fade in and out in various customizable sequences. The feature wall lends the space “a sense of excitement and movement that’s hard to put a price tag on.”
