I might be able to help with this.
The most obvious thing that comes to mind is ‘sphere location’. You can place the hex mesh at random locations on the sphere with that.
I’m not a big Blender guru, so I don’t really know the equivalent to a color ramp, but you can also use ‘sample texture’ to compute things like hex visibility or position.
Your animation is a little short, maybe you can describe what your goal is?
