I know! I was confuzzled for a bit as I tried to work out when brenda had got so good at coding, and then realised it was actually Brenda-with-a-capital-’B’.

Crikey bonzah mate. What do you think the chances are of that happening? Two of them?

Thank you so much Brenda - and especially for showing me that the text could be moved outside the for loop.

If you want the dots to be evenly spaced, try this (two changes from your code):

void draw() {
translate(width/2, height/2);

background(125);
//point(x,y); //(a centre point)
for (int i=1; i<=pts; i++) {
angle = i*(360.0/pts); // needs 360.0 not 360 to force floating point division
px = x+cos(radians(angle))*radius;
py = y+sin(radians(angle))*radius;
point(px,py);
}
pts++;
text(pts,-10,-10); // moved from inside the for loop
if (pts == 360) {
pts = 1;
}
}
