Hi.

You could get some blacklight paint and go over parts of you side art. Or do the lettering on you marquee (on top of the glass)
that way if you don't like how it looks you can remove it.
You could also get some side art ( make sure it has a laminate over it, all of classic arcadegrafix.com's does) and use the b. light paint and a fine hair paint roller to give it a thin coat. ( make sure you use the b. light paint that drys clear) you can get it here

)
Another thing you can do is make a blacklight fountain. ( spencer gifts has cool ones i like the beer tap one like this
http://www.zymetrical.com/product.asp?3=710 To make it glow get a couple of thick highlight markers. remove the ink sticks and cut them into 1 inch pieces. fill the fountain and let the ink sticks soak for a day. then just fish them out and your fountain will be blacklight responsive. Damn I really need a gameroom.

I hope this helps, Ron
