Symmetry © Wayne Moran 2007 Definition: In common usage generally conveys two primary meanings. The first is an imprecise sense of harmonious or aesthetically-pleasing proportionality and balance; such that it reflects beauty or perfection. The second meaning is a precise and well-defined concept of balance or "patterned self-similarity" that can be demonstrated or proved according to the rules of a formal system: by geometry, through physics or otherwise. From wiki This building is the Landmark Center (www.landmarkcenter.org) in St Paul Minnesota. A group of local photographers were going to come here for a photography outing in a few days. So I needed to get out and make sure there was something interesting to shoot.
