I created my own video panel as a pixel mapping experiment
I used WS2811 LED strips, these are digitally addressable RGB strips with 8bit dimming for each pixel
The strips were controlled using Pixel Invaders (http://pixelinvaders.ch/) to generate the effects, which outputs ArtNet to an Arduino Mega with Ethernet Shield then gets converted to SPI and sent to the LED’s.
Below is a video of the strips in use as part of my UNLV scenic design final.
