    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.

Give it at least 10 seconds to start looking nice. After about a minute it's desktop-background-worthy :)

Searching for f(x,y,t) this time. If you have more patience then add operators, parens and increase string length in the slice.

Clever concept, like some old tv grasping at transmissions.
u/DataMeta

Haha, Xen
u/tomxor

Nice analogy :) like a TV into the computable universe, infinite channel! (sorta)
u/21medals

Why the space in between each character of E?
u/tomxor

Because -- and ++ are assignment operators, and I cannot allow those on loops variables X and Y. It's basically cheaper in chars to pad with spaces than test for this with a regex.
