(Ignore the Virtual Pinball screenshot, I couldn't find a good picture, looks much better with the proper Gottlieb reels and lighting though.)
Has flashers behind the eyes which of course are screened off so only the circles light up. Cool little touch to an already awesome backglass. They shut off once the game is started and come back on once the game is over.
Although two player glasses are usually collector preferable since you can see more of the artwork, I actually prefer this one as the extra set of reels adds even more to the techy-ness of the backglass while being nicely incorporated into the artwork.
ALSO: The name "Magnotron" > "Duotron" times a billion, of course. It's so badass!
