Circle Packing Mosaic
The image is rendered as non-overlapping circles of varying size, each filled with the color beneath it. Small circles cluster on detail and big ones cover flat areas, creating a bubbly mosaic.

Why it happens
Circles are placed greedily, largest first, wherever they fit without overlapping, with radius limited by local detail, and each takes the average color of its area.
