    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!

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.

Example of looping with recursion, trailing off as time goes by

u/joeytwiddle

For the first 9 seconds it calls u() 250 times per frame (on average), after that just once per frame
u/hollo47

Looks like these M.C. Escher lithographies, I love the feel of it!
