Another challenge, a fairly easy one if you know a little trig for starters:

Given this attaced image,
write the code that will produce
a similar image.

some hints:

the image is showimg of @O
(thats the letter O there not number 0)

the only trig functions i use are sin() and cos()


let see how fast you can whip this out.
