How would you redo these BBC designs #challenge

I really like these BBC idents (between shows). How would you recreate them? I know the 3d ones look really hard.

Are these all procedurally generated?

we don’t know, some look more programmable than others

I guess some of them are procedurally generated with tools like Houdini and notch.

The rendering makes it complex but I’m sure some movements or patterns are combination of available algorithms and can be recreated in processing!
