Alternative diffusing method.

[st2000]

Not an issue, but I don't think github has a project "suggestion box" feature.
I really like this build and the results look great. Currently, I am trying to back light an old stain glass window with an addressable LED array in a bid to make wall art. I too do not want to make this wall art overly thick. I am still experimenting, but plan to use photography flash diffusing cloth. It is inexpensive, readily available in large sizes and very light. I may use 1 layer or wrap it around a wooden frame to form 2 layers with a gap in the middle.
