Just completed my first build. I used a wire shelving rack as the core with 3' poles in the front and 6' poles in the rear. I built the surround from 1/4" acx plywood.
I managed to find an old Dell 19" LCD at the thrift store which seems to be the perfect size for this build. The marquee is a 10" android tablet using software that turns it into a second monitor.
I bought two sets of wifi controlled lights, and wrote some backend code to take a screenshot of the marquee, figures out the dominant color and sets the lights to match. I'm still working on this as a lot of the colors end up whitish, but it definitely makes for a more immersive experience.
