Here's a real treat, folks. Chief and I loved these things! They're the "water ripple" projectors that cast those lovely patterns under the sea. The projector in the foreground is angled down, the farther is up a few degrees. The way the ripples crossed over each other was pure magic.

I think these were in the transition from sea to space. LOOK at all of that cool stuff! Hey! There's a disk on the floor!
Sweet! The disks would rotate in front of the projector lens.
That pattern is great. The disks were heavy and probably 1/2 think. Maybe 3/4. Maybe I have no idea what I'm talking about.
"Water Ripple Reflection" Damn I miss that ride.
