A similar tool is called L-Studio, an Android app that lets you define a drawing grammar and use it as a recurrent drawing tool.

The app is called L-System Studio (Lindenmayer Fractals) https://play.google.com/store/apps/details?id=com.playposse....

Thank you for the correction!

Whether you like this or feel like it's not as powerful as you'd like, try http://recursivedrawing.com/ in a similar vein with discussion here: https://news.ycombinator.com/item?id=3951255. It's simultaneously simpler and more expressive than this tool in my opinion.

Amazing demo video buried in those comments: http://vimeo.com/41822151

Very simple and expressive, indeed!

Unfortunately no SSL, so I won't be enabling JS.

You can clone the repo, audit the code, then host it yourself if you want to: https://github.com/electronicwhisper/recursive-drawing/tree/...

If you're worried about someone MITM'ing you and injecting malicious code on random webpages you should be using a VPN.

Indeed, my tool is very much centered around the drawing experience. It's all about the pen strokes, not the placement of established shapes.

This lets you make something that looks oddly similar to a street map of a city: https://imgur.com/a/aE3RbgK

Recursion scale closer to 1 and ‘flexible angle’ result in much crazier pasta, for me.

The game Engare [1] is another enjoyable way to explore this kind of thing - a more spirographical approach though.

'Spirographical'. Excellent word. I knew immediately what you were saying.

I love this game's music.

What is it, an L-system?

onemoresoop• 7 years ago

from wikipedia:

An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures.

This is nice - is there any way to find out who wrote it?

slx262• 7 years ago

in fact, this was already posted in the past [https://news.ycombinator.com/item?id=17600629], which is when I suggested them to include recursive drawing, but that user doesn't seem to be active around here

you can go to their blog / contact us if you need to get in touch with them

Wow holy shit. I had forgotten about this thread which is indeed what put the seed in my brain for adding recursive drawing.

I knew I read about it somewhere and the idea go wedged in my brain until it was implemented. That's pretty much how everything works :) But it's kind of cool to see the exact moment of inception from months ago.

Yeah I remember googling this and not being able to stop thinking about it. The same was true for tessellations and radial symmetry before that.

What a fitting conclusion that we both find ourselves here with your suggestion implemented. I'm indeed not active on HN but I do show up when my servers get hammered by it :).

Thank you for the idea, I hope you're satisfied with the implementation :)

If you go to the pro facet of the site (https://pro.mandalagaba.com) you'll see you can mix radial symmetry, with tessellation, with recursion... If you like it all, you can have it all in one pen stroke :).

Let's just say that baking recursion in was extremely complex. I had to sit down in front of my computer for a couple of hours every night for a good 2 months to have it implemented and free of bugs.

So... you got any other good ideas? :)

MeowMcLulz7• 7 years ago

It is I, the implementor. Showing up here on HN having been summoned by my servers screaming for resources.

If you want to get in touch, feel free to send an email to the contact address on the website and I'll get it.

I was able to completely lock up my Mac with some odd combo of settings, had to quit Safari (after about 30 seconds of everything being dead). Didn't think that was possible in a browser.

MeowMcLulz7• 7 years ago

Oh it's very much possible. Threading, GPU, webassembly. Browsers are as desirable today for computing as the machine they are running on.

You might be interested on an article I wrote a year ago which made a splash here on HN https://news.ycombinator.com/item?id=16509947

Very nice :) Take a look at this one too: https://i.imgur.com/8MhUbHh.jpg

Trying to use this with Firefox 66.0.3 on Windows 10 desktop. Have uBlock Origin but tried disabling it. Every few seconds, it refreshes. What am I doing wrong, and how do I, as a user, find instructions to fix what I'm doing wrong? I would like to draw or generate something.

MeowMcLulz7• 7 years ago

Hey I'm the guy who wrote this, sorry about the trouble. Do you have an unconventional connection at the moment? (Cell hotspot, proxy or VPN)?

I'm happy to go into the tech details if you want, but I'd look there first.

neogodless3• 7 years ago

I tried Chrome and it's the same behavior as Firefox, so connection could be it. It's not terribly weird - corporate LAN. There could be some element of "proxy" in there, but I'm not using a VPN right now.

On my phone, on the Wifi, it does seem to work, though! (But the Wifi has different rules; for example, they block Facebook, LinkedIn, etc on Wifi, but not on the LAN.)

The only other thing - I know they block some cloud storage on the LAN. Is that a requirement?

Looking in Dev Tools, I don't specifically see anything blocked or failing to load.

(edited to add) Do you require Third Party Cookies? I see a lot of Warnings in the console: "Request to access cookie or storage... was blocked because we are blocking all third-party storage access requests and content blocking is enabled."
