Made a collaborative, persistent state Mondrian-style painting editor. Feedback welcome!

Love the idea, silly as it is! What came before, the app idea or the pun?

Pun

Does this use the DeStijl manifesto. There were actual rules about how to use color and lines.

Awesome! I haven't had this much fun since r/Place.

The ultimate territorial acquisition strategy seems to be as follows:

- Pick a desired colour

- Choose a place to found your empire, ideally somewhere with a lot of large rectangles and a colour that takes few clicks to turn to yours

- Left click tiles to capture them for your colour

- Right click those same tiles many times to subdivide them into areas much smaller. What took you 1 click to capture will now take anyone else hundreds!

This doesn't seem to work at all for me, but I don't see any error messages in the console or anything... I just see a dark gray screen with an (i) on the top left (with the instructions), but nothing seems to have any effect (left or right clicking, using the scroll wheel or dragging the mouse with left or right click) don't seem to have any effect. The only effect I'm seeing is right clicking on the page shows a "[CLIENT TRIGGER] Right-click at (123.456, 789.012)" message in the console log.

I can see that there's some traffic (for example, I see some WSS on socket.io, and some XHR for /state, /clients, /checksum) but it doesn't seem to change anything on the screen.

looks like people somehow deleted everything, reset it to starting position

By the time I arrived to this it was so subdivided it no longer looked like a Mondrian and someone had managed to write "ASS" in the lower left corner by changing the colors of adjacent rectangles.

oh it's gone through a lot of iterations - I have seen Among Us characters, people clearing out the canvas down to 8 rectangles, entire thing going one color, had to delete a few obscenities, etc

Doesn’t seem to work, just unclicks whatever I click.

Same. I thought I was in a battle of wills, and I guess I was, just not the way I thought.

My edits disappear either right away, or I can recolor for 20 seconds and then it gets reloaded with the previous colors.

I think I'm having stability issues with lots of users, will try to figure it out, sorry

It looks like you need to batch your updates and not tie them directly to UI actions, imo!

Cool project!

OMG I thought I was fighting with someone really fast.

I thought so too! Maybe it was true

No need to apologize, just wanted to let you know there is an issue.

{"message":"Too many connections. Please try again later."} coming from the socket.io websocket. Good luck with the hug of death, and sorry for my spam clicking!

people wrote scripts to color everything one color, had to implement some limits, but I think should be good now

Sadly that is unequivocally a very fun thing to do, and honestly I was considering trying it before I came and checked the HN thread haha

sorry about that and the merges! I'm stopping now :)

that was a fun way to spend the past hours

No worries lol. Learning experience for me :)

Was it you that was trying to get the German flag on there? If so, wow great job! Got a few screenshots!

https://f.toi.sh/21juin-mmondrian.png

yes hahah did it twice, I think OP nuked it once

it was a simple rule, if y < 1/3, black, if y < 2/3, ...

I went on there with my young child, and there was a german flag on there, just not the 2000s german flag, more like 1940s german flag.

Really we need some common sense censorship on that site someone made for fun.

> Really we need some common sense censorship on that site someone made for fun.

neural_thing was really good about resetting if anything went awry. It's just 1 person's toy project they wanted to share. Set your expectations of investment at that level. Detecting swasticas + every other symbol that might taint the mind of your young child is a rather hard task, and yet you expect it to be done for free for you.

I can give them a break for missing one case, and point the blame for that solely at the internet in general for trying to ruin a purely fun thing with hate.

This is not just an issue of my child, for example, if a German user were to open that site in public, they would be found guilty of hate speech, amongst dozens of localities : https://en.wikipedia.org/wiki/Bans_on_Nazi_symbols. Also in California, where speech is free but is not free of consequences.

I don't make the rules here, I just don't want this guy to go to jail for his fun project.

Maybe Anubis-style proof of work?

oooh good idea thanks

implemented, thanks for the idea, love it

I like this very much. BUT: What I cannot save I do not remember (quoth the Old Guy). Any way to save these images as SVG. (Screen grabs are less satisfactory.)

I have a script that generates images every hour, will adapt it to let people save states!

I can't seem to pan, it would be nice if the zooming would zoom in to the mouse location. (I did manage to write HI near the left edge though.)

Removing lines doesn't seem to work, it flashes out but then stays in.

Have to click on black lines. They can be moved too.

I did, it flashes out, then it comes back in.

merging squares was the most satisfying part for me, but there is a bug sometimes when merging, the server refuses to do it even though it's valid

yeah - merging has been tricky to nail down, definitely the thing that's gone through the most iterations so far

I would love to know more about it! you should make a blog post

it's been a learning experience for sure, but my blog is really not a good place for a technical story like this. i'll think about where i might be able to post it

Is the website dead?

Fixed now

Misread this as MMOndain [0] and thought it was going to have to do with the Ultima games

I thought I was going to learn about the category of endofunctors
