Following my recent 2D image morphing demos, I've been thinking of visualizing the process as a single 3D shape.

From a pile of shit, new life grows. Conway's Game of Life running independently in the 3 colour channels in 64x64 cells with wrap-around topology.
Not much new code here, just added image loading capability to my old pile-up demo of 2D cellular automata.

Let's try a fancier/heavier morphing idea. Each point from one image is paired with the nearest point from the other. Then we can linearly interpolate the position of each to move between the two pictures.

A basic algorithm for a basic guy: find the edge points in the binary image and change their colour to that of the target image. Rinse and repeat until the edge no longer moves.

New Year's Redactions
My earlier text redaction demos were done in my OpenGL setup, using a pixelation effect overlaid on a text document. This was rather simple, but it required some manual tweaking to align the pixelation grid with the text. I've now redone the effect in text mode using Python.

Rule/Yule 30 cellular automaton with a "band-pass" filter every few iterations. Done in the Bash shell using bitwise math, so each row/state is a single number of 63 bits.

Hej tatta gorem! Koska ATK-laitteiden tuottama teksti on nykyään in, hip ja wow, niin tehtiin @noira_musti kanssa oma runogeneraattori. Uniikit tekstit löytyvät osoitteesta algoristo.com/markoviinike... tai nettisivujeni kautta.

Another blow-up view of the Apollonian spheres, now dropping on a concave surface to gather all the jetsam together. This is what I had in mind when writing the first drop demo, and the model just needed a bit of refinement for the differently sized balls.

Making Apollonian gaskets usually follows a key rule of iterated function systems: each iteration should make the thing smaller. With inversions, this means going from the outside to the inside of inverting circles.
However, it's possible to make valid gaskets using a lopsided configuration, where
