Words, images, or colours that appeal to the mind, eye, or body. A communication between an artist and a participant that extends beyond the immediate into the realm of shared experience. One that calls forth in the participant deeply motivated emotions. It is that which makes my butt wheez. Sorta like this chair.
Art is a cumulative collection of past human emotion embodied in the artifact.
Experiencing it projects its message into the future. Art is anyhting that you look at. He is a fairly quiet dude who spends lots of time in a meadow. She likes to eat rice crispies every now and then. Art is hard.
