Nature is 'floodlighting' the valley.  The sun highlights one field after another as clouds roll overhead. This is unrelated to fractal geometry but a peep into that subject reveals how it deals in certain shapes and details therein.. One classic shape is similar to an inkblot but they certainly don't end there. Fractal computer art is very curious.

B Mandelbrot, who was seriously into fractals, died recently and his bio was revealed in the Sydney Herald this week.
Fractal. A rough or fragmented geometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced/size copy of the whole.
Clouds are not spheres, coastlines are not circles, bark is not smooth, nor does lightening travel in straight lines. Mondelbrot.

Mathematics...the chaotic and fractal systems and the Julia set are the domain of these experts.
