Now THAT looks useful, especially the auto-calibration. I like the name similarity too.
I'd suspect the helicopters would bump each other in minor air disturbances, unless they were so far away from each other that they'd be unable to make a dense display.
It uses LEDs with PIC processors on each LED, the smart LEDs are then connected to each other in a parallel arrangement I believe. The power to the LEDs is used both as current for the LEDs as well as a data line.
Upon start up the LEDs becon out their unique ID, negotiated by communicating over their data lines. A webcam is then used to detect the position of the LEDs by their ID.
So effectively the chain of LEDs can be arbitrarily scattered, and by detecting the position of the LEDs in 3D space, their software then allows images etc. to be displayed.
