it sounds like your really close!hope so.. convinced now its a quirk with the second layer setup texture stuff/the shader.
if your texture is showing ok in gDEB and the updates are happening at the right time. the problem must either be coming from the second layer
sometimes strip everything back by block commenting huge chunks of my code out

Quotehave you thought about recording another take of your demo again closer up + in the dark? "lights out edition"yeah as soon as i get my good camera back of my friend i will upload a much better video i tried with the lights out with my phone but there was far too much glare..
i guess with other colours, or the ability to vary "fade out" (greyscale?) some other doors would open up.
with a limited palette.. colour cycling?
from the left-field sure i've seen a fully lit OpenGL LED simulation somewhere before too, with the API lined up run the same the "demo" in a virtual scenario
