I’m thinking again about the surface quality of things, in particular, sculpture. The surface of a sculpture, if it isn’t the integral sculptural material itself, is conditioned by these other qualities:

Ornament attracts the eye in a flowing motion, in a variety of all directions. it relaxes the eye muscles and the vision and focus.

Pattern is repetitious, which causes the eye to jump and move, the moiré of pattern and strobe effects of Op Art. It activates the eye’s movement, and is stressful to vision and focus.

Texture is a randomness of pattern, unintentional, the eye wanders without intent, abstractly, into a seeking of imagery to focus onto, the paranoia critical method of Dali. It can be visually restful while also being mentally stressful

Color is the corporeality of an object contained by the field of vision, a visual object is entirely color and nothing else. Impressionist.
