Art has been used IN rituals for thousands of years. You probably have recognized art and design in your personal rituals. Rituals like going to a religious service, the mural you see on your daily commute, the design on your favorite coffee mug you use every morning. Even rituals like walking the dog, and the trusty Nike swoosh on the shoes you grab overtime to perform this ritual.
How often does art BECOME a ritual though? Incorporating a dose of creating can be incredibly rewarding. There may not be any monetary gains from a daily doodle, but it can be a great stress reliever or just a good daily laugh. A doodle a day, keeps the doctor at bay... I think that is how it goes.
