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

Doesn't work on android, just see boxes with X inside :(

just replace 𝘼𝙋𝙀𝙍𝙏𝙐𝙍𝙀 with Aperture. Which also is a bit heavy on the byte count.

Didn't know yours when I did mine (https://www.dwitter.net/d/6216), but yours is waaaay better than mine - I tried to do the dots in the radar and couldn't figure it out. :) BTW, kudos for using the "space" inside the x.beginPath call, great idea!
