Solace is an algorithm that generates artworks of sand dunes. It draws hundreds of thousands of tiny points according to a probability distribution calculated from the positions of the dunes.
The logic to divide the dunes into light and dark sides is simple, but produces some interesting chaotic behaviour. These are details that weren't hard-coded but emerge organically, such as the patterns on the spines of the dunes or the stripes around their bases.
Please note that the algorithm can take some time to run, especially when the number of dunes is high.
