Art: Beautiful Randomness
Those who create art often have a motive and thirst to express something that they see as important in the world. Perhaps the motivation to create art is self-expression. It could also be the means the artist adopts to expose the world to a unique form of beauty that only they can see. Or maybe they draw a phalis on the inside wall of a restroom stall at the Olive Garden because they're an immature douche. For good or ill, motivation and a desire to express some self learned truth can lead to art.
Art can be also be accidental in the same kind of way you impregnate your girlfriend after using a steel belted condom. The chaotically random nature of the universe that allowed a perferated condom to pass through Trojan's quality control and into your wallet is the same randomness that generates the beauty of a sunset, or the dappled light reflecting off of capped mountains. So, art can also be a product of random chance.
