    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.

Autograph shrinking into a black hole #path2d (fixed version that can't roll a negative number for the first number)

u/Tesseract

Nice. .join(" ") is unnecessary since commas are allowed as separators in paths.
u/Agnes

Oh, interesting! The Mozilla documentation of SVG paths used commas for every other number for the C command so I didn't think you could use them everywhere.
u/lewdev

Change .join(" ") to .join` ` to reduce two characters.
