I agree, I really like the idea but the 2D ones seem a bit forced to me - not that aesthetic. The 3D ones on the other hand are beautiful and have a much more natural feel.

I think it's important that the graphs don't perfectly fit and that the equations look simple (though some aren't really). It might be taking her work too far, but if you think of art as a way of communicating, it's nice to think of messages about how math can guide the real world, but rarely does the real world fully fit.
