I generated a new set of pictures for my living-room today. This time I created an abstract art generator that creates random curves and draws circles that follow them, I also made it choose a base color at random and create the colors in the HSB colorspace depending on the size of the curve

Here is the processing sketch I used to generate the curves, in case you want to create your own

import processing.pdf.*;
float[] x = new float[16];
float[] y = new float[16];
float[] r = new float[16];

int bc = 0;

void setup() {
  size(594, 840);
  smooth();
  reset();
  noLoop();
}

void reset() {
    for( int i=0; i<16; i++) {
    x[i] = random(width-150) + 75;
    y[i] = random(height-150) + 75;
    r[i] = random(80) + 10;
  }  
  r[13]=0;
  r[14]=0;
  r[15]=0;

  bc = int(random(255));

}

void draw() {
  beginRecord(PDF, "curve-####.pdf");
  colorMode(HSB);
  background(255);
  stroke(0);
  for( int i=0; i<12; i++) {
    for( int j=0; j<80; j++) {

      float t = j / 80.0;
      float ex = curvePoint( x[i], x[i+1], x[i+2], x[i+3], t );
      float ey = curvePoint( y[i], y[i+1], y[i+2], y[i+3], t );
      float er = curvePoint( r[i], r[i+1], r[i+2], r[i+3], t );

      fill((bc + map(er, 10, 80, 0, 80))%255, 255,255);

      ellipse( ex, ey, er, er );
    }
  } 
  endRecord();
}

void keyPressed() {
  reset();
  redraw();
}
