I could easily see something like that used to etch the artwork into a CP, then layering Plex over it.
Same with the marquee or side art, but the cabinet would just about have to be a woody.
Actually, for the marquee, I could see taking some veneer, mounting it to plex on the backside, using the laser to etch a design on the front (or hell, on the back even), such that when lit from behind you see the design because of the differing thickness of wood.
If you etched it on the back, when the inside light was off, the from would just be flat, which could have some interesting possibilities too.
