So if you saw the halftime show (no comment...) of the Packers' big win yesterday, you saw dancers wearing costumes with LED light strips on them. They flashed in different colors, coordinated across the dancers. How did they do that? RF receivers in each costume?
I'm imagining each costume having the LEDs, a pretty decent battery pack, and a microprocessor attached to an RF receiver, and then a central processor somewhere sending out the patterns.
(Yes, this post was largely just an excuse to brag about the Packers)
