    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.

Almost #xmas

u/veubeke

PS: the dweet doesn’t work in Chrome 71 – autoplaying speech has been deprecated and drawing big emojis is broken
u/veubeke

I reported the bug and they fixed it only partially so this remains broken. See https://bugs.chromium.org/p/chromium/issues/…

355/113 is a famous approximation of pi and here we need pi/5 which is perfect as 5 divides 355 giving 71/113

Yeah I didn't need the precision but it was an interesting coincidence and I had extra chars :)
