I am so happy to have finally undertaken programming again, all thanks to the helpful processing language, community and books. Thank you. I accidentaly made my first game, and now I want to try to do the ecosystem practice task in Shiffmans book.

So this is my first problem I have not been able to solve myself. How to close this in a curvy way?

2. float[] tid = new float[12];
3. float angle;
4. void setup() {
5.   size(800, 800);
6.   for (int i=0;i<11;i++) {
7.     tid[i] = random(0, 1);
8.   }
9.   colorMode(HSB);
10.  noStroke();
11. angle = 360 / 8;
12. }
13. 
    
14. void draw() {
15.   background(255);
16. 
    
17.   fill(int(noise(tid[1])*360), 255, 200);
18.   beginShape();
19. 
    
20.   for (int i=1;i<12;i++) {
21.     curveVertex(width/3 + 200 * cos(radians(angle*i))+noise(tid[i])*300, height/3 + 200 * sin(radians(angle*i))+noise(tid[i-1])*300);
22.   }
23.    endShape(CLOSE);
24.   for (int i=0;i<11;i++) {
25.     tid[i] += random(0, 0.01);
26.   }
27. }
