Fimo fractals and fancy fiber

Evilmadscientist has a well-documented project on drawing (stretching, not sketching) fimo into fractal patterns. You can start with a set of four triangular rods, stacked together into one larger triangle, strech them out to make them skinny, stack them in with four other similar assemblies, and iterate to make fractals. Aside from the fractal part, this technique is identical to how photonic crystal fibers (PCF) are formed, which got me thinking…
