Design is the fundamental soul of a man-made creation that ends up expressing itself in successive outer layers of the product or service. The iMac is not just the color or translucence or the shape.
To design is much more than simply to assemble, to order, or even to edit: it is to add value and meaning, to illuminate, to simplify.
There's design, and there's art. Good design is total harmony. There's designer than nature - if you look at a branch or a leaf.
