More spiraling. Jason sent links to information about Fibonacci's Spiral (scroll down) and the Golden Mean. Very interesting reading—especially as the golden ratio relates to art. Also, there's this book: The Curves of Life: Being an Account of Spiral Formations and Their Application to Growth in Nature, to Science, and to Art: With Special Reference. The special reference sounds especially special.

Also, meg's mom spotted a spiraly shirt and clipped it before reading my post.
