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.
uncompressed: for(p in x)this[p[0]+p[6]]=p;x[fc](0,0,q=c.width=c.height=98,q);for(x[gC]='lighter',i=20;i--;s=2**i)i>5?x[fc](S(t)*55+i*6,40,4,9,x[fy]=hsl(${i*39},39%,2%):x[da](c,-s,-s,b=q+s*2,b)
x is CanvasRenderingContext2D (something you can get by calling canvas.getContext()). It is one of the shorthand variables predefined in dwitter.
