Just do demonstrate off the back of my drawing circles without sine and cosine... https://scratch.mit.edu/projects/625460152/ A lot of comments were pointing towards, why not just draw a radial line out... Well... here's why! If I draw the line using sine and cosine even if I only iterate by 1º each time I end up with loads of gaps and lots of repeated pixels stamped. Of course I could reduce the amount it increments by each time but that will mean it'll take more cycles. Smaller radius' obviously require fewer increments. I'm sure there's some clever maths doable, whereby you'd calculate the circumference and then work out the amount of degrees you need to increment by. But you'd still be writing pixels that you've already written. I accept it's a pretty cool effect, but generally not something you're usually after!
Love the discussion in the parent project. I tried to create one in 38 moves, similar method to my YinYang. It could be reduced to 37 moves but i like the effect of filling the center last.
