I actually made this program so that i could be the first person to post in the exhibition part of the forum but i guess i were too slow. :(
But i still like the final images and i did in fact put some time into tweaking this and i have had this idea in my head all day so i was probably gonna post it anyways (maybe).
So here it is (right click on the images and select "View Image")

Of course i do :)

class Point{
float x;
float y;
color c;
Point child;
int leng;
boolean moved;
public Point(float nx,float ny){
    x = nx;
    y = ny;
    leng = 40;
    c = color(random(255), random(255),random(255),20);
    child = null;
    moved = true;
}
void tick(){
    if(child != null){
      stroke(c);
      if(moved)
        line(x,y,child.x,child.y);
      float distance = sqrt( sq(child.y-y)+sq(child.x-x));
      child.moved = false;
      if(distance >leng){
        float angle = atan2(child.y-y,child.x-x);
        child.x -= cos(angle)*3;//(distance-leng);
        child.y -= sin(angle)*3;//(distance-leng);
        child.moved = true;
      }
      child.tick();
    }
};
public void addChild(){
    if(child == null){
      float a = random(TWO_PI);
      child = new Point(random(width),random(height));
    }
    else{
      child.addChild();
    }
}
}

Actually this looks better:

class Point{
float x;
float y;
color c;
Point child;
int leng;
boolean moved;
public Point(float nx,float ny){
    x = nx;
    y = ny;
    leng = 60;
    c = color(random(255), random(255),random(255),20);
    child = null;
    moved = true;
}
void tick(){
    if(child != null){
      stroke(c);
      if(moved)
        line(x,y,child.x,child.y);
      float distance = sqrt( sq(child.y-y)+sq(child.x-x));
      child.moved = false;
      if(distance >leng){
        float angle = atan2(child.y-y,child.x-x);
        child.x -= cos(angle)*3;//(distance-leng);
        child.y -= sin(angle)*3;//(distance-leng);
        child.moved = true;
      }else if( distance < leng*2/3){
          float angle = atan2(child.y-y,child.x-x);
        child.x += cos(angle)*3;
        child.y += sin(angle)*3;
        child.moved = true;
      }
      child.tick();
    }
};
public void addChild(){
    if(child == null){
      float a = random(TWO_PI);
      child = new Point(random(width),random(height));
    }
    else{
      child.addChild();
    }
}
}

      dstx = 11;
     }else{
      dstx = width-11;
     }
}
if(dsty >height-10 || dsty<10){
    dsta =atan2(-sin(dsta),cos(dsta));
    if(dsty <10){
      dsty = 11;
     }else{
      dsty = height-11;
     }
}
float ang = atan2(dsty-p.y,dstx-p.x);
p.x += cos(ang)*3;
