    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.

Weird... I wonder why it's stopped working...
u/magna

It still works for me. macOS + Chrome.
u/joeytwiddle

MacOS and Chrome here. The unicode char (was it 👾?) appears to get stripped while loading. If I paste it in between the "", then it works. Perhaps Dwitter loads differently on different pages?
