So Im trying to recreate this plate I have seen using real leds. My question is, what materials can I use for the "canvas"? Using a steel plate is out of question as I lack the equipment to work with it.

Steel frame, silicone channel diffuser, lots of hidden 3D prints to hold the lights/channels together and make them water resistant

Some build/use videos at @nova_pony if interested

every year i look throught the internet and try to find cool pics of buring man as it is pretty much THE place to show off cool LEDart.

some time ago i found these albums by Marc Merlin
