How would a zen master divide a Toblerone bar? He would snap it so that the proportion between the longer and shorter chunk is equal to the proportion between the whole bar and the longer chunk. Thus the zen master has achieved Phi.

Phi (φ), or the golden ratio,describes the harmonious ratio (a+b)/a = a/b, which is about 1.618.

This java applet shows how to divide and subdivide a rectangle in golden ratio. The result is fractal-like, might have achieved Phi, but not quite yet divine.
