Nucleus finding, Misiurewicz point finding, and a bit of guesswork, combine for successful O(period) automatic Julia morphing.

Improving image quality by avoiding catastrophic cancellations.

A self-published physical artifact of reaction-diffusion.

Based on a SIGGRAPH 2001 paper, with blue noise generated by inverse Fourier transform.

Endosymbiosis simulation leads to sticky boid-like flocks that behave like super-organisms.
