for those wondering, what is on display are the level sets (3d contours) of a neural network.

this is a very cool use of shaders for raytracing, but it is not terribly informative.

Why is it moving?

It's a 4-dimensional object. The animation doesn't show the object moving, it just shows progressive cross-sections of the object. If you stop the animation, you can choose which layer of the object to view with the slider.

Edit: Not to derail the thread, but here's another post about 4D visualization toys. https://news.ycombinator.com/item?id=14471931

Otherwise you'd only see the level set for one specific value. Looping through the values allows to see the entire shape over time.
