Skylight, curtain, surround, vault… it would all be possible. Combine it with your fire code @zranger and wow!
The window above is an old 2030 single pane I took out of my 1950s house. It still has the aluminum surround so the leds stand away from the glass just a bit, adding to the apparent depth effect.
I can just see that skylight… beautiful. But yee gads!!!, another project.
