I was in total awe when i saw this a couple years ago. We came back and i went on a pic-taking frenzie lol. I had a gut feeling this was a true rarebird. I didn't even realize it had switches until i looked at Joe's link above. If it's still there in a few years when i can get my own job i may ask the owner if i could have it for $100 or so. He probably has no idea how rare this is or maybe not even know what this is. Obviously it's a light fixture but weren't these used in store window displays to advertise the new Mazda lamps back in the day? About how old would you guess this to be?
I could just see taking it and wireing up some sorta custom chase/flash controller for it
