| This is incredible, thank you for sharing

| Thanks!

| Amazing.

| It seems he did not share any source code, though.

| This wasn't rocket science (at least my part). I cringe now to

| missing the point, and this retro effect is deliberate?

| Here is another interesting technique for generating algorithmic
| art, from Renato Budinich: https://renatobudinich.com/create-
| random-images-with-randima....
|
| It is a beautiful algorithm using a simple two-step procedure.
| The first step involves taking a random gray-valued mask image
| and applying the path-finding procedure of the Easy Path Wavelet
| Transform (EPWT) to it. This path-finding technique is greedy and
| aims to obtain a succession of vectorized pixel values with
| minimal variation. It does this by always picking the next point
| (among the available neighbors) that yields the minimum absolute
| value difference in pixel values. This approach helps it select
| regions with similar pixel values before making a jump to pixels
| with significantly lighter or darker regions.
|
| Once a random path of say length N is obtained, a random color
| map (think of one from matplotlib or seaborn) is applied, with
| each point k in the path mapped to the k/N point in the color
| map. Et voila! A gorgeous image appears.
|
| I've been using this as cover art for my personalized radio
| station software (https://github.com/pncnmnp/phoenix10.1).

| Interesting those PDF files (links in the bottom).

| A long time ago, I wrote IrisGL code for the mathematician George

| published this book:
| https://en.wikipedia.org/wiki/A_Topological_Picturebook, which is
| worth a look, and he was forever sketching Reimann manifolds on
| scraps of paper with a fountain pen. Which is quite a trick. I
| kick myself for not hanging onto one.
|
| He maintains what for me is a very nostalgic old-internet webpage
| at https://new.math.uiuc.edu. There are links at the bottom to
| web versions of his computer animations.
|
| Edit: If you do click on the animations, make sure to try the
| different commands like "morph" and "skin".
