I have tons of old-skool arcade marquees (mostly early- to mid- 80's). The few later-era marquees I have are for games like Punkshot and Double Dragon II (and III?). I know, they are old too, but they are the most "recent" titles I have.
I made a lightbox (it held one "standard-size" marquee at a time) only to realize that I should have designed it to hold TWO marquees (on opposite sides). Unfortuntately, there was really no place in my home to put the lightbox, so I sold it on ebay.
Next time I build a light box, I'm gonna use flourescent bulbs. One reason I sold my old lightbox is because I used incandescent bulbs and even with low-wattage bulbs and ventilation holes, it just got TOO DAMN HOT.
I don't have many paper/cardboard inlays (I forget what you call them) that surround the monitor and are under the glass. I have Section Z... and maybe 1-2 others. I sold a bunch of them because they are sooooo fragile and I didn't have a good method for storing them. I wish I took the time to store them properly, but I was too lazy (all I need were some big pieces of cardboard to sandwhich them between).
I would love to make an illuminated wall of marquees, but I fear that it would look ugly. Plus, it would be pretty tough to design something that was slim, looked nice, and accomodated all the different-sized marquees. Simple rows / columns would be boring... I'd want to create a pattern... like masons do with walls and floor tiles...
Of course, that might look ugly as well...
