All design evokes something. Colours, font, margin and spacing, edges and borders - it all evokes some things that came before it more than others, and the relationship with the human body and its feeling of agoraphobia and claustrophobia, kinematics - whether controls are pointy or smooth, hard or soft, stiff or slick or springy, continuous or with detents - it all adds up to an aesthetic.

You can't help but have design. You know when things don't "feel" right. When something feels flimsy instead of solid; when it's haphazard instead of regular. And when the design is exceptionally poor, chaotic, that too is a design - a kind of mad, insane design, or primitive and naive, unskilled - it always evokes something.
