Scott Miller built a hula hoop with Bluetooth, an inertial measurement unit, a 32-bit processor, an 8-bit processor, and a slew of individually addressable LEDs. It makes wild patterns when you move.
Scott's "normal" company, with all of its ham radio equipment, is Argent Data Systems. The hula hoops are Hyperion Hoops.
You can buy a hoop. They are also on Facebook or you can watch the mesmerizing lightshow on YouTube (also here and here).
Yes, the hula hoop does speak DMX512, doesn't everybody?
