Tessellations are regular patterns of shapes fitting snugly together to fill the page, without overlapping to form a symmetrical pattern. M.C.Escher had tessellations of people and animals neatly fitting together making interesting patterns. I drew this tessellation of the cobra pose, and after a few hours today at the Northern California Regional Yoga Asana Championships I have confirmed to myself that the human eye is good at seeing things which aren't really there and yogis are good at contorting the body into shapes that don't seem possible. Both create a feeling of well being and balance for the mind and the body. It is a beautiful thing.
