Self Spiral

I have had a more-or-less accomplished version of this image in my head for a ery long time. I have finally gotten it out in the real world.

I hope I will not learn that the same symbol already exists and stands for something horrible.

Source code, mostly C and POV-Ray.

High resolution (4k) version (3.1 Mo).

The cheesy animation in in GIF format (4.3 Mo), in H.264 in Matroska (18 Mo), in high-quality WebM (13 Mo), on YouTube.

A square version with transparent background, with the alpha channel as a monochrome mask and vectorized with potrace.

Consider the image itself to be under CC BY 2.0
