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
ebay.com link: 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?
