This a ''Hexagonal led panel'' 3D model, modelled, textured and rendered in blender cycles 3.5.
Instead of making it a normal led, with some rgb colors, I decided to give it a more modern look and textured it with some anime backgrounds.
With those anime colors, you're scene can look more real because of the emission, even more aesthetic if you find they way to use them.
DISCLAIMER: This is not a procedural generator. That means that this is a simple 3D model, that can be edited in your program (blender better).
