Hamid Naderi Yeganeh is an artist which draws pictures with mathematical equations: Wikipedia, X, Instagram, YouTube.

Morpho buttterfly is one of his artworks (X, Instagram):

The present repository reproduces this work with C.

The program uses OpenMP to parallelize calculations and STB library to create the images.

The program:
- generates butterfly picture (by changing NB_RUNS, it can be done several times, to evaluate durations), and
- generates heatmaps of intermediate calculations.

See images below.
