    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.

My first thought was: "Oh this REALLY looks like Vicks drops" :)

I thought of a Roleaux rotor for some reason :/

works after hovering it

u/h3rmanj

probably don't work in older browsers either
u/BirdsTweetCodersDweet

It doesn't work till you hover on it, because v and y have no default values
u/BirdsTweetCodersDweet

c.width=568 t?0:(v=0,y=0) c.onmousemove=e=>{v=e.x,y=e.y} x.beginPath() for(i=88;i--;x.moveTo(300+S(t+i)*200,150+C(t)*C(i)*150),x.lineTo(v,y)) x.stroke() is too long, but fixes the hover issue - maybe you can golf it ;)

Awesome! I managed to shorten it down to 129 if you want to add something to it: v=160;s=20;for(i=60*v;i--;l=(i%v))m=(i/v)|0,k=1+S(C(l/15)/C(m/17)+t*4),x.fillStyle=R(n=k*v+m*2,n+m,n+k*v),x.fillRect(l*s,m*s,s,s)
