Initially I had a different idea for this one. There is a wolfenstein made of LEDs and effects in the wall. Most of the walls and effects do not follow the idea I had initially in mind. To go near one of these effect walls and see that they are also made up of LEDs. LEDs inside LEDs. Only one kind of wall follows this idea, the one with some fuzzy blinking lights, just go and stick near that wall and see the main LED pixeled gfx in big, made up from smaller pixel gfx LED that makes the whole primary display. Like secondary displays inside primary ones. It never worked well with the other effects and I couldn't draw a good led in just 4*4 pixels.
The demo is a bit interactive. You just have to use the arrow keys to move around the maze and see all the effects. Hope you like it. It was great for my to code this one after so much time of inactivity. Well, I should be studying or searching for a job now

p.s. The primary display is deliberately damaged (has malfunctioning lines). Each LED has it's unique R,G or B color as stated in the rules, just changing the shades. I hope I didn't screw up with some other rule.
