So what I'm doing is...

I'm trying to create visual pattern that will be used for a sort of memory. For the most part, I have the code I need to turn on the LED's, but my problem, now is choosing what material I need to display the LED's. Its similar to how a light bulb has a glass dome to cover the watts, but this is much safer obviously. I was given a suggestion to used frosted acrylic. So while I search for a transparent material, I'll just keep reviewing my code
