    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.

I ran out of characters. But this is cool... i guess

u/13thptr

you can remove the brackets of the for loop, doing for(i=999;i--;) is 1 byte shorter over your approach and 1920 can be approximated with 2e3

thanks, ill keep that in mind for future dweets

I'm trying to learn the c.width thing, how come you did |=? Isn't is the same as =0?
