Future Spaians,

I was lucky enough to find a really nice Future Spa but it had lots of small issues. I have been fixing these issues, one by one, and I am really beginning to enjoy the game play.

I am missing whatever magic holographic piece goes on the back of the backglass and in front of the 'Future Spa' lamps in the backbox. I am considering ordering this as a substitute:

8"X25" Diffraction Grating Roll Sheet Double Axis 13,500 l/mm Physics Light

Has anyone tried this particular item? Will the diffraction grating give the same or similar effect of the original backglass?

"6" x 12" Diffraction Grating Roll Sheet Double Axis 13,500 l/in Physics Light"

Thanks for reminding me. I just ordered this. It will take two to four weeks to get and will let you know how it looks on Future Spa when it gets here:

I got my diffraction grating today. The pictures do not do it justice. I was going to use double sided tape, but changed my mind and went with clear shipping tape cut into thin strips. I only taped down the sides. That seemed to suffice.

The diffraction grating adds depth and splits the white light into a star pattern and all of the colors of the rainbow like a prism. It was certainly worth the eight dollars I paid for it. Here is the eBay link again if anybody wants to order one for their Future Spa.

I haven't the slightest idea. I've never seen an original piece on a Future Spa. This new one is all sparkly and glittery in front of the 'FUTURE SPA' lamps. Your eyeballs can't help but be drawn to the light show. And isn't that the purpose of a pinball backglass? I like it. I'm keeping it this way.

Thanks Jethro for the information!
