Looks like The Andromeda Strain.

I checked out some of the other videos and their website and this looks really cool. I've attempted liquid light shows with an overhead projector and can never get it to turn out right. These liquid discs look like an easy alternative for a similar effect.

They are excellent for that yes! There are a few people making unofficial wheels too that you can find on eBay.

Here's a discussion about an outdoor called Fruit Salad Light Show that used a bunch of Optikinetics gear for shows in the 90's that might also interest you. https://ozrics.proboards.com/thread/2204/light-show

See also "Innerstrings" (Chris Tomsett) who has a vast arsenal of Optikinetics gear that he uses along with live video processing. Really great.

Good shout. I was going to mention him but couldn't find any video of his oil wheel work. His combination of analogue and digital is really nice.

Both of these links are very cool and now I'm doing some eBay browsing

Wow, yeah, that is strikingly similar! The video in the submission seems a little more dynamic, though, and a bit more relaxing.

Another comment mentioned the two projectors in the patent — and based also on the "reminds me on an aurora" mentioned in the article, I suspect it's a kind of slow crossfade between the "slides" that makes the Auroratone more relaxing.
