Scientists have studied trees depicted in various works of art and found they contain fractals, following relatively simple mathematical rules also found in branching patterns in nature.

Although prevalent in art, the fractal repetition of patterns represents an artistic challenge. For instance, many people have attempted to fake Pollock’s fractals and failed.

By using fractal math to calculate how the branches of trees are depicted in art, researchers can put a number on what makes for a realistic tree.
