WS2812B Matrix with 300 LEDs

During the last few weeks I wanted to play a bit with WS2812B LED strips (30 LEDs per meter) and of course I wanted to build an LED matrix with it :-). I ordered 10m WS2812B LED strips and a 5V / 20A power supply, build a wooden frame for them and used an Arduino with the FastLED library to control the matrix. What you see here is the ColorPalette example of the FastLED library.
Btw, sorry for vertical video :-/!
