    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

this graph shows the fast convergence of u/Xen 's algorithm for golden ratio

u/katkip

I don't understand anything
u/pavel

A and B are sequential Fibonacci numbers, their ratio tends to the golden ratio.

amazing remix, as always :D
u/cantelope

was wondering where you've been.. i shudder to think what you can make within 1kb. feel free to remix my work on codegolf.tk if you like.
u/pavel

Thanks man! I was on vacation in New Zealand for a month with just my phone. I'll check out codegolf.tk, I do like optimizing down to 140.

this one doesn’t even need the fillrule. Was just looking into other cycloids and Lissajous figures, only to end up with a circle.
