Corrupted snowflakes

A short time before Christmas I tried to generate some abstract snowflakes. The result is… surprising but still interesting. In a first time I made a very straight black and white version. Although the images produced don’t really look like snowflakes, a nice feeling occurs if you look at the center and refresh the page (at least it works for me).
Then I made a second version, smoother and less messy. The last version which is simply multiple layers of the second experiment with a bit of color.
I like theses sketches as they are examples of how very few code can produce some complex and good-looking images.
