Design process: establishing the main proportions, grids and library of geometric shapes. 

However, people are not math, people are not built from grids. We are irregular, not always logical, and, foremost, we are human. 

So: humanisation – define parts and areas, and make the needed adjustments to shapes and forms, although being mathematically correct. Basically, changing it into something that pleases the eye.

Much effort has been made to achieve equal parts minimalism, aesthetics and legibility.
