    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.

Corona Panic

Funny idea. On font-size 8em you cannot see the mouths of anyone so I think it works better with 6 or 7.

It works fine with Apple’s emojis. Unfortunately, I don’t have a quick way to test on multiple devices.

In my country, the cases grow extremely fast.

morphing text. I comprimised on the precision of some constants, so some of the timing will go out of sync after a few runs.
