Flux capacitor! It was the first word that came in my mind when I saw this picture, as it reminded me somehow of Dr Brown's flux capacitor from Back to the Future. Remember that one.
This picture was, and this shall come as no surprise, given my other photos, taken over the Namibian dessert nearby Sossusvlei. The dunes formed by the "flux" of the wind, remain amazing. Nature has so much beauty to offer.
In post, I increased the shadows slightly to provide more structure in the darker parts, while also adding a touch of saturation to bring out the redness of the sand.
