    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.

Slightly more interesting depth-sorted spinning tower

I just realised there's literally no reason to do mod 2*pi at the end of the P function, wow
u/Agnes

And there's a map(e=>e) in there! Must have been asleep when I programmed this.

Move Mouse To X-Ray #mouse

Clever idea. If you do fill you can re-use the rect you did for clipping. onmousemove=e=>T=e.x;c.width=568;with(x)for(font="7cm'",i=2;i--;i&&clip(fill(rect(0,0,T,568))))fillText(i?"🧔":"💀",92,250+S(t*9)*(T>500)*4)
