Orange Rectangles


 void setup() {
   size(480, 480 );
   smooth();
 }
  
 void draw() {
   // ellipse(mouseX, mouseY, 80, 80);
   fill( 255, 200, 8 );
   rect( mouseX, mouseY, 80, 80 );
 }


Swapping mouseX and mouseY


 void setup() {
   size(480, 480 );
   smooth();
 }
  
 void draw() {
   // ellipse(mouseX, mouseY, 80, 80);
   fill( 255, 200, 8 );
   rect( mouseY, mouseX, 80, 80 );
 }


Squares and Circles


void setup() {
    size( 500, 500 );
    smooth();
}

void draw() {
   fill( 200, 100, 100 );
   ellipse( mouseX, mouseY, 80, 80 );
   fill( 200, 0, 250 ); 
   rect( mouseX, mouseY, 80, 80 );

}


Squares move Horizontally, Circles Vertically


void setup() {
    size( 500, 500 );
    smooth();
}

void draw() {
   fill( 200, 100, 100 );
   ellipse( 100, mouseY, 80, 80 );
   fill( 200, 0, 250 ); 
   rect( mouseX, 100, 80, 80 );

}


Random Circles


void setup() {
    size( 500, 500 );
    smooth();
}

void draw() {
   fill( 200, 150, 200 );
   ellipse( random(500), random(500), 80, 80 );
   // fill( 200, 0, 250 ); 
   // rect( mouseX, 100, 80, 80 );

}


Random Circles with Varying Size and Color


void setup() {
    size( 500, 500 );
    smooth();
}

void draw() {
   fill( 200, random(255), mouseX/2 );
   ellipse( random(500), random(500), mouseX, mouseX );
   // fill( 200, 0, 250 ); 
   // rect( mouseX, 100, 80, 80 );

}


Random Circles in Square Areas


void setup() {
    size( 500, 500 );
    smooth();
}

void draw() {
   fill( 200, random(255), mouseX/2 );
   ellipse( random(100,200), random(100,200), mouseX, mouseX );

   fill( 200, mouseX/2, random(255) );
   ellipse( random(300,400), random(300,400), mouseX, mouseX );

}
