Yes finally got an idea for my next party, floor controlled LEDs!
“Our flagship product, the Disco Dance Floor Controller Board is capable of controlling up to 192 LEDs (with 4-bit intensity control) and 64 binary switches via a USB interface. Using the included source code, a refresh rate of 17 frames per second is easily achieved. With some environment specific modifications to the software, rates in excess of 30 frames per second may be achieved. Multiple boards may be connected together using USB hubs to control additional LEDs and switches.”
