Not exactly pixels, having fun with lib8tion and random controlling 16 1W LEDs. RF remotely triggers the strobe effect, LEDs controlled via shift registers.

Hey! Very cool to see non-pixel implementation here.
Also: crazy bright, right?
yes, so much so that I had to make an array of 3mm LEDs just for testing. Fire up the 1W ones and you see spots for a while afterwards. Made it hard to read/type 
Ahhh shift registers. I’ve had my fun with them lol
