    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.

Massive props to JWinslow in the Discord for doing almost all of the golfing! The last 15 or so characters were removable because 1.57 is an OK approximation of Pi/2 and because the dimensions were scalable by four in the transform.

This may be possible in 140 but I couldn't put the time in today. If you figure out how, post it as a remix!!!

This ain't much, but it helps: with(x)A=a=>Math.random()*40|0,B=0|A()/8,setTransform(1,0,0,1,A()*48,A()*27),rotate(Math.PI*B/2),clearRect(-24,-13.5,48,27),B&&fillRect(-20,-13.5,40,27)

Very similar to something I already did but I like how this is a single expression.

Feel free to remix this with your own head, hand and foot emojis, and change the value of b to make them rotate at different speeds.
