This thing you see in the video on the next page (and in the picture above) is called the "Swarm Light." It's a series of little LEDs hung in sequence along three clusters of grids, lit up in order by a computer to display simulated collective movement, like a swarm of bees. It's very interesting, both as a display for a programmed algorithm, and just as an art project. All together, the display costs $180,000 -- no small chunk of change.
If you do watch the video, you can see that the whole thing is run by an iPhone. rAndom International created their own internal app for Apple's device to run their various installations, and the iPhone app can dim the lights, adjust them to ambient light conditions and switch through the various modes. Just another awesome use of the iPhone.
