Can anybody help me with this?

2. 
   
3. 
   
4. void setup(){
5.   size(300,300);
6.   background(255,255,255);
7. }
8. 
   
9. void draw(){
10.   
11.   //Coordenadas
12.   float x = random(0,300);
13.   float y = random(0,300);
14.   
15.   //Colores
16. float r = random(0,255);
17. float g = random(0,255);
18. float b = random(0,255);
19.   
20.   //Radio de circulo
21.   float d = random(0,100);
22.   
23.   stroke(r,g,b);
24.   fill(r+100,g+50,b+40);
25.   ellipse(x,y,d,d);
26. }

But what I to do is that every drop grow until it disappears...

2. 
   
3. float x = 150;
4. float y = 150;
5. 
   
6. int d = 100;
7. 
   
8.   //Colores
9. float r = random(0,255);
10. float g = random(0,255);
11. float b = random(0,255);
12. 
    
13. void setup(){
14.   size(300,300);
15.   background(255,255,255);
16. }
17. 
    
18. void draw(){
19.   
20.   d = d + 1;
21.   
22.   stroke(r,g,b);
23.   fill(r+30,g+40,b+15);
24.   ellipse(x,y,d,d);
25. }

Some thing like that but with every circle on the screen

And when d < 200 it  disappears.

HELP!!

Can I?

What I want to do is rotate each line in a different angle.

Thanks.

 

I really don't know why do I get this error, I was making an exercise and it doesn't work.
