I quite like the idea of an equation, because it doesn't point only to art or to science, but has that universal kind of feel for any aspect of life. Artist is of course an equation with his art, meaning that an artist is not balanced if she does not create. But so is everybody else - any person finds its own approach, their own process that balances things out, to get to that cosmic equation that is so much spoken of in Nature and in human mind, and in relation of the two.

Equation, in turn, is a mathematical concept which lends itself quite logically to visual representation. This is a thing to think about, but here's a quick sketch made the other day of some kind of logical construction found in real life:

Basically, two dudes covering the roof of a building - one below, another on the top. The circular motion of the bucket connects the two, and so does their own co-motions. The lower man goes to the car on our right to fill the bucket, the top man goes to the left out of the picture to do the roof work. Then the process repeats.
