Ensōs

I recently became interested in the ensō, the Japanese word for circle.  In Japanese calligraphy, the depiction of an ensō is a meditative practice in which the mind is free to let the spirit create.  As a symbol of enlightenment, Zen Buddhists believe the artist's character is exposed in their depiction of the ensō.

For my drawing class I decided to continue with the generative form/illusions theme and use ensōs as a base component.  Initially I intended to transform each ensō into an impossible circle like this, however I eventually decided to only hint towards some impossibility.
