I have seen this site some days ago (reddit maybe?) and I really like the concept! The design is very clean! One feature I'd like: A way to slow down the render so we can see the whole generation in slow-motion.

And once you can slow down the generation, it would also be lovely to highlight the line of code being executed as the picture was drawn!

These are great!

Also reminds me of the Forth Haiku Salon: https://forthsalon.appspot.com/

For anyone interested about this kind of things, I did something a bit similar for 3d voxel rendering: https://voxeltoy.com/, also inspired by shadertoy.

Ahhh, love this site. I own an axidraw pen plotter, and because I'm feeling generous, I'll print every sketch made by people in this HN thread. <3

I fear the method I used here will be really inefficient on a pen plotter though: https://turtletoy.net/turtle/63b170ed47

(Lots of useless moves happen while the pen is up)

Go to this one [1], change the GEAR_NUM to like 30 and enjoy the rendering 1: https://turtletoy.net/turtle/9ddc6d4dc5

Tweaking the value of PI2 is a lot of fun..

While TurtleToy is way more advanced, few years ago I built a small webapp that uses nested CSS to make recursive images: https://zetabee.com/weave/

Click [Help] button to get an idea of how it works. It was heavily inspired by Structure Synth but written from scratch to work with CSS3 in a modern browser.

Is it possible to get vector files of some sort out of these? .SVG, .AI, .PDF, or something similar would be awesome. Edit: I meant directly from the site. I could do it from my desktop using python. PS, this is awesome!

Yes, there is a download button for each drawing

Thanks, I confused it for an upload button.

If you're into this, you might also be interested in robotic pen plotters. This article from last year kicked off a serious new hobby for me which combines code/art/robotics/etc and has been a ton of fun.

I won my first (and only) programming contest in Logo. Fun to see the idea alive.

I am highly impressed that some of these actually implement wireframe hidden surface removal:
