Howdy,
So . . . when I was a youngin' and still dreamed of someday having my own pinball machine, I bought a translite from Twilight Zone and built a box for it to hang on the wall. I've also got a light fixture that can be mounted behind it, so you can back light it.
It's kinda strange, but pretty cool looking. Not your standard wall art, that's for sure. Anyway - I put it up on Craigslist for $80. If anyone on the board wants it, they can take it for $50. I'm pretty sure the translite alone is worth that. Add my extremely novice level woodworking/painting skills on top of that . . . what a deal.
