Had a few minutes this morning free before going into work to make a reality @joker’s suggestion. Thinking about @takitus’s stargate for his dad, I do need to etch the water ripples into the blue acrylic, but just to knock it out, here it is. Design on a different device so tonight I’ll post the file in the Free Laser Designs.
Proofgrade 1/4" clear acrylic with an overlay of a PNG version of an SVG file of the Stargate. Cut the center button out of 1/8" blue acrylic from Inventibles. It totally works!
They glow in this. I think I can work with a little to get the symbols to glow a little better. Keep the bottom making on and paint the masking to have a darker backgound of the glowing symbols. Should have turned the lights out for the video because it shows up much better IRL!
