What is #つぶやきProcessing?

'#つぶやきProcessing' is the hashtag on Twitter. And this hashtag express that it has short (under Twitter limitation) source code and that result.

ほぼ同コード
void setup() {
size(600, 600);
blendMode(DIFFERENCE);
}

void draw() {
clear();
for (int i = 4; i < 15; i++) {
float r = i * frameCount * 0.02 % TWO_PI;
ellipse(300 + i * 10.0 * cos(r), 300 + i * 10.0 * sin(r), i*50.0, i*50.0);
}

You can see many amazing works by the '#つぶやきProcessing' wizards on @TweetProcessing.
There are many cool Processing codes. They post tweets with not only Processing Java mode but Python mode, also p5.js.

There are many code shortening techniques and are many visual effects that you'll stare in wonder. 

Originated in Japan.

'つぶやき' means mutter in Japanese. And it also means tweet on Twitter, too.
They pronounce it like 'Tsu bu ya ki'.

The founder of '#つぶやきProcessing' hashtag is @Hau_kun.
He said 'つぶやきProcessing is a challenge that creates art with Processing under one tweet text length limitation'.

He said 'I'm dreaming of Sir Daniel Shiffman would post to this someday' in Processing community Day Tokyo 2020.
I believe that will come true soon.

Hi! How can I help?? 🚂 🌈

Example of mine.

void setup() {
  size(636, 636);
  blendMode(DIFFERENCE);
  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);
  }
}
