Ha, I've thought about adding a small fan too. Definitely need to do that.

Do you have a picture of the installation at the science museum?

The color just rotates through the oklab space (change hue only).

We had this at Clemson University about 10 years ago. I think the whole design came out of an MIT lab though. There's video of it still up here: https://www.clemsongis.org/clemson-sandbox

Naturally I can only find a photo of the sand table (and a cool piece of halite in the background!).

It’s at the Dynamic Earth exhibit at the Sudbury Nickel Mine. This was a few years ago.

it's not the exact science museum experience mentioned, but a quick Google search for "sand table video augment" pulled up a few, and this was the first one I found: https://share.google/89A6x4yfaw5a4hOuh

When the first Xbox were getting long in the tooth, I believe people were repurposing the motion tracking bar as the mechanism to measure the topography of the sand table. That, coupled with a video projector mounted over the top of the sand table provides the additional colors and elevation lines. (And of course a bit of cool software to process and produce the image.)

I've seen the sand table installation before, pretty cool. I was interested in how they did the fluid in particular. Thanks anyway.
