Great find! I have one too, purchased solely on the strength of the art, um, package (thanks Vid, for pointing that out) Rumor has it that Williams originally had a color wheel designed for the area behind the giant squirting fountain on the backglass put the bean counters nixxed it-too expensive. I plan on trying some color changing LEDs (GASP!) behind the fountain on ours. Should look cool!
I look forward to keeping up with your progress.
Cheers!
