    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.

Why does deleting the code still let it work? is it overriding the contents of u()?
u/BuRRak

what the fuck
u/BuRRak

This still blows my mind and i don't understand it at all
u/BuRRak

Oh, it makes sense now, you are using invalid characters that are not visible. Very clever!

u/ZerataX

yeah after the location is set once, it doesn't matter if you remove the code. more or less just letter substitution: https://jsfiddle.net/Lcjo35h4/1/
u/ZerataX

btw those are Hangul Fillers and Variation Selectors. since they are all supposed to be applied to other characters they don't show up on their own.
