    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.

This is a set of 5 isochronous cycloidal pendulums, based on equations from Wikipedia. https://en.wikipedia.org/wiki/Cycloid and Rem088roy's illustration. Each pendulum takes the same amount of time to reach the 'bottom' because the bottom end of each one follows a Tautochrone Curve. https://en.wikipedia.org/wiki/Tautochrone_Cu… #cycloid #physics #pendulum #huygens

I've just spent a long time running this down, but with firefox-62/ubuntu-18, I have an issue where garbage is spoken at the end of each emoji name. The issue is an unterminated string copy in espeak-ng which should be fixed in newer versions; see https://github.com/espeak-ng/espeak-ng/issue…
