What is #つぶやきProcessing?

'#つぶやきProcessing' is a popular Twitter hashtag used to showcase creative coding works where the entire source code and its visual output are contained within a single tweet's character limit.

On the @TweetProcessing account, you’ll find a gallery of stunning works created by these code-wizards. From Processing (Java mode) to Python and p5.js, the community pushes the boundaries of what’s possible with minimal code.

You will be mesmerized by the clever code-shortening techniques and the breathtaking visual effects they achieve.

The Origins

The movement originated in Japan. In Japanese, 'つぶやき' (pronounced "tsu-bu-ya-ki") means "muttering" or "murmuring," and it is the standard term for a "tweet" on Twitter.

The hashtag was founded by @Hau_kun, who defines the challenge as "the art of creating visuals with Processing under the strict constraints of a single tweet."

At Processing Community Day Tokyo 2020, he shared his dream: "I hope that someday, the legendary Daniel Shiffman will join us and post his own #つぶやきProcessing." I believe that dream will come true soon.

Hi! How can I help?? 🚂 🌈

  noLoop();
}

void draw() {
  for (float i = 0; i < PI; i += 0.05) {
    float r = sin(i)*200;
    ellipse(i*200, r+318, r, r);
    ellipse(i*200, -r+318, r, r);
  }
