Certain layouts and compositions look right, others seem wrong. We can see it, but we can’t point our finger to exactly why.

Pi governs the shapes of rounded shapes, , waves and much more. The elegance of a circle is simple. But it is governed by a complex set of harmonics and ratios that all relate to each other. Beautiful designs have them, beautiful music has them. In most cases, we only appreciate the end result without grasping the underlying logic.
