"When I look at any icon I encounter, I look at both presentation and metaphor. Does this make sense? Is it free of extraneous detail? Is it well crafted? For example, when I see the circle with the red slash (which means something is prohibited) occasionally used for “delete” it’s like chalk on a blackboard! When I see a carefully articulated fresh take on a concept, I’m delighted."
Susan Kare, designer of the original Mac icons and beyond.
