5. size(600,600);
6. smooth();
7. strokeWeight(5);
8. x = 0;
9. y = 0;

17. stroke(255);
18. fill(0);
19. triangle(width/2,0,0,height,width,height);
20. ellipseMode(CENTER);
21. if(mouseX != pmouseX || mouseY != pmouseY)
22. {
23. x = pmouseX;
24. y = pmouseY;
25. }
26. else if(mouse==true)
27. {
28. noStroke();
