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?

    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.
          • neural_thing 2 weeks ago
            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.
            • brookst 2 weeks ago
              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

                  OMG I thought I was fighting with someone really fast.
                  • riidom 2 weeks ago
                    I thought so too! Maybe it was true
                  • mmazing 2 weeks ago
                    It looks like you need to batch your updates and not tie them directly to UI actions, imo!

                    Cool project!

                    • brulard 2 weeks ago
                      No need to apologize, just wanted to let you know there is an issue.
                  • graypegg 2 weeks ago
                    {"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!
                    • neural_thing 2 weeks ago
                      people wrote scripts to color everything one color, had to implement some limits, but I think should be good now
                      • graypegg 2 weeks ago
                        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

                          Maybe Anubis-style proof of work?
                        • leoff 2 weeks ago
                          sorry about that and the merges! I'm stopping now :)

                          that was a fun way to spend the past hours

                    • dmwood 2 weeks ago
                      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.)
                      • neural_thing 2 weeks ago
                        I have a script that generates images every hour, will adapt it to let people save states!
                      • dunham 2 weeks ago
                        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.
                          • ponsfrilus 2 weeks ago
                            Have to click on black lines. They can be moved too.
                            • remram 2 weeks ago
                              I did, it flashes out, then it comes back in.
                          • leoff 2 weeks ago
                            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
                            • neural_thing 2 weeks ago
                              yeah - merging has been tricky to nail down, definitely the thing that's gone through the most iterations so far
                              • leoff 2 weeks ago
                                I would love to know more about it! you should make a blog post
                                • neural_thing 2 weeks ago
                                  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?

                              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
