Didn't see the Super Bowl, and can't comment on the technology used, but I've been looking into Xylobands, http://xylobands.com/ http://xylobands.com/, that have been used by Coldplay in some of their concerts. Technically, that's a LED (monochrone, later they used multicolor LEDS) with a radio receiver. Radio transmitters were installed throughout the stadium, controlling specific LEDs to go one or off. See https://www.youtube.com/watch?v=JficYgaK8j8 https://www.youtube.com/watch?v=JficYgaK8j8 for some background video and the use in the song Charlie Brown in the Mylo Xyloto tour.
