One of the assignments for my design technology class was to make a lightbox. The only restrictions were that it had to be lit internally and we had to show our process. I figured the rpf might like this. This is what I came up with. It was designed in AutoCad and is made out of 1/8" basswood cut with a laser cutter. I had a few LEDs left over from my portal gun build so I used two of each color. The portals have a piece of frosted plexiglass behind them. I want to make another one that's bigger and has more LEDs in it.
