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 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)
