You are right, these are 2D shapes.
I thought of having the ability of controlling the shapes height. kind of having them dance, each different height.
For that a 2D shape would be strange, since im skewing the scale of the 3d looking 2d shape.

That’s why I thought an actual extrusion should be applied, I was looking for extrusion methods.
You are right, it would be hard to imitate.
