Now the moment I've been waiting for - powering it on for the first time (and praying everything works!).
Here are some shots with the lights off - it is impossible to get a good picture but you get the idea. The marquee really pops and everything looks better than I imagined it.
I am VERY happy with the results. I still have a few very minor things left to do (software tweaking mostly and I also have to figure out a back door even though you can't see it) but this project is about 99% finished.
I'll post a video of it working when I get a chance and other miscellaneous stuff when it pops into my head.
