Here's the Kinetic Light Installation in operation at KLAX
The color of the lighted pylons changes, of course, and aren't random, but they have different choreography programs running (curtesy of Couatl, our Python scripting engine), the screenshot shows the "Stars and Stripes" program, which is usually reserved for special occasions (like 9/11), but we liked it, so we run it every day.
There are other programs running, and each program is selected at random, which makes for an interesting sight...
P.S.
Before anyone asks, there's no "Work in Progress / 13", reasons for this should be fairly obvious
