I used to recall my personal discovery of the mathematical rhythm in nature, and was totally fascinated by how nature embeds specific proportions in its beings. It seemed to be then that if I can master Pi and Phi, I’d probably rule the world, create master pieces in design, and stuff like that.
Well, spirals would be one of the many examples of mathematical proportions at work in nature – and this site has just about every spiral you can imagine! While I’m not exactly sure how that would be of use, it’s still a pretty (literally) good time-gnawer just browsing through the many pictures!
