Yes they're plastic spheres a couple+ inches across.. inside each one is a pcb with three 5050 leds and a WS2811 driver chip. That part I got on ebay pre-assembled. I actually have some new ones I got which contain 6 LEDs per ball. I'll def post more shots tomorrow when we're home. But yea the setup in the vdeo is over 10 feet high and round 5 across.. I didn't have that much space to spread them out.
