I have always found it intuitive and fun to think geometrically and spatially. Many complex things become clear through geometric modeling.

I have even found it therapeutic to visualy represent feelings in the form of colored shapes, and manipulate these shapes in order to tune moods or eliminate pain.

We don't mean anything by introducing this therapeutic method to you. It's just an illustration that simple shapes can be more useful than mathematical models on paper. Geometric modeling can be done in the mind for recreation, therapy, or because it's FUN.
