    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.

Omitting the space in 99%50% does not work in Safari, everything is black.

this one doesn’t even need the fillrule. Was just looking into other cycloids and Lissajous figures, only to end up with a circle.
