How does symmetry relate to tessellations?
I believe all Artwork must have a degree of symmetry and balance, be it landscape-abstract-or portrait, and mosaic is no different. The Universe exists with balance, and the Equilibrium of the minds-eye depicts this as to the emotions you feel while gazing at the art. I feel symmetry bring you into a microcosm of the work, A lack of symmetry or balance give you a feeling of helter-skelter.
