The big and small of the desert
As my guide, Ahmed, and I trekked through the Sahara along the Algerian border I was really taken in by the beauty. I love the clean, mathematical lines that trail into noise where animals have tread on them. The wind, rain and gravity effect the sand in very specific ways. The math behind them is so enormous that we have problems modeling their behavior with supercomputers, and yet you can see that mathematical precision in the sand. No matter how elegant those macro forces are the animals come plodding through leaving a noisy wake in the sand.
