I: Kasimir Malewitsch's bird

Originally based on the task to recreate a piece of Kasimir Malewitsch, I accidentally arranged forms more in a way a bird looks like and decided to continue that approach instead.

Result

Algorithm

  void setup() {
size(400,600);
  }

void draw(){
 background (255);

//black square
noStroke();
fill(0,0,0);
rect(100,50,200,200);

//body red
noStroke();
fill(255, 25, 64);
rect(110,220,250,200);

//feathers
noStroke();
fill(102,230,255);
triangle(136,282,151,282,140,295);

//feathers
noStroke();
fill(102,230,255);
triangle(180,310,220,310,200,300);

//feathers
noStroke();
fill(102,230,255);
triangle(200,340,3400,340,300,300);

//feathers
noStroke();
fill(102,230,255);
triangle(270,390,300,390,250,370);

//yellow rectangle
noStroke();
fill(255,204,102);
rect(40,50,80,150);

//brown Square
noStroke();
fill(66,20,12);
rect(120,200,50,50);

//green circle
stroke(77,255,106);
strokeWeight(10);
noFill();
ellipse(195,50,50,50);

//spout details
strokeCap(SQUARE);
stroke(255,51,187);
strokeWeight(10);
line(59,79,59,160);

stroke(255,51,153);
strokeWeight(10);
line(85,100,85,140);

stroke(255,153,255);
strokeWeight(10);
line(95,150,95,160);

//legs
stroke(255,255,0);
strokeWeight(10);
line(215,420,215,520);

stroke(255,255,0);
strokeWeight(10);
line(235,420,235,520);
 text( "x: " + mouseX + " y: " + mouseY, mouseX, mouseY );
}

II: Cute Bauhaus

Here recreation was also the topic, refined with some first simple interaction.

Result

Algorithm

 void setup() {
size(500,500);
frameRate(60);
}

void draw() {
background (255);
line(20,30,70,80);
line(0,0,100,100);

size(500, 500);
background(300, 200, 100);
strokeWeight(50);
line(100, 500, 400, 80);
line(5, 400, 400, 330);

noFill();
stroke(0, 0, 200);
strokeWeight(5);
ellipse(mouseX, mouseY, 400, 300);

//here i draw a red square
noStroke();
fill(255,0,0);
rect(100,150,150,150);

//circle
fill(0);
ellipse(300,355,150,150);

//triangle
fill(255,255,0);
beginShape();
vertex(250,150);
vertex(400,150);
vertex(325,mouseY);
endShape();

rect(10, 10, 30, 30);

noFill();
strokeWeight(40);
rect(400, 300, 100, 50);
}

    }
  }
}

III: Cat's Eyes

My first nested for loops sketch with some slight random function adventures that resulted in unexpected "eye like" circles, maybe cat's eyes. I would like to use those eyes in a future sketch!

Result

Algorithm

int gap=100;

void setup(){
  size(800,600);
  background(0,230,115);
  smooth(8);
}

void draw(){
  float speed= sin(1)*30;
  frameRate(speed);
  for(int i=1; i<=7; i+=1) {
    for (int j=1; j<=5; j+=1){
      int xPos=i*gap;
      int yPos=j*gap;
      float ellWidth=random(100);
      float ellHeight=random(100);
      
      float R=random(100,255);
      float G=random(100,255);
      float B=random(100,255);
      
      noStroke();
      fill(R,G,B);
      ellipse(xPos,yPos,ellWidth,ellHeight);
    }
  }
}

IV: Butterflies

Again in this sketch I benefited from unexpected "errors" while trying to get more into arrays and their use. Originally I just wanted to create different rectangular forms that are kept in the frame like fish in an aquarium and step back when they reach the boarder. But what i actually got was some pixelated flickering things, that, I guess could be seen in an abstract pixel art universe as butterflies. Obviously I still don't understand arrays and there consequences for following code lines fully, but I like the result and kept it.

Result

Algorithm

 int num=50;            //number of butterflies, but actually around 5 "form" one...
int stepLength=10;     //tempo of them

int x[]= new int [num];
int y[]= new int [num];
int w[]= new int [num];
int h[]= new int [num];

void setup() {
  rectMode(CENTER);
  size(1280,720);
  background(255);
  noStroke();
  
  for(int i=0; i<x.length; i++){
    x[i]=(int)random(width);         // random position of the butterflies 
    y[i]=(int)random(height);
    w[i]=(int)random(20,80);
    h[i]=(int)random(20,80);
  }
}

void draw() {
  background(255);
  rectMode(CENTER);
  
    
   for(int i=0; i<x.length-1; i++){
    int newX=x[i]+=random(-stepLength,stepLength);        //move the butterflies
    int newY=y[i]+=random(-stepLength,stepLength);
    
      if(newX<0) newX = width;
      else if(newX>width) newX = 0;
     if(newY<0) newY = height;                       //keep them 
      else if(newY>height) newY = height;
      
      x = append(x, newX);
      y = append(y, newY);         // I guess this results in "butterfly effect"
    
    if(x.length > num){
    x = subset(x, 1);
    y = subset(y, 1);
    
    rect(x[i],y[i],w[i],h[i]);
  }
    fill(x[i],y[i],150);              //mellow colours
  }
}
