I visited the Detroit Science Center & spotted an Asteroids/Lunar Lander cabinet. What game could this be? I've seen Lunar Lander in a few science museums...but where's the side art???
Laser Spirograph marquee?

Hey, it's a science experiment! In an Atari cab! Certainly a better life for an Atari B&W X-Y cab than many of their unfortunate demises...
There's a laser in the control panel. It's pointing at a pair of mirrors, each of which is mounted askew on a rotating disk. The 2 knobs control the RPM of the 2 disks. Then the light must bounce off a couple of mirrors inside the cab & gets rear-projected onto a flat screen where the tube once was.
Playing with the knobs gives you all sorts of funky polar coordinates images like a cardioid, as well as your favorite Spirograph-type images.
Pretty neat. Wonder what became of the guts...? I checked the back side for any Atari badges or stamps, but it's clean & plain & black.
