One of the main characters in John Updike's novel Roger's Version is Dale, a computer science graduate student seeking some fingerprint of God in fractal structures (and also funding for his research from the Harvard Divinity School). The novel includes discussions of cellular automata, fractal trees, the Koch curve, and the Mandelbrot set. In a sequence of computer zooms, Dale believes he sees the hand of God, if only feetingly.
Theology notwithstanding, Updike has gotten the basic mathematics right. For example,
"A tree, like a craggy mountain or a Gothic cathedral, exhibits the quality of 'scaling' - its parts tend to repeat in their various scales the same forms." (pg 236)
