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.
x.fillRect(0,0,q=2e3,q);if(!t){w=[];for(i=q;i--;)w.push({a:i/321,d:500-i/9})}x.globalAlpha=.1;for(o of w){x.clearRect(960+S(o.a,d=o.d)*d,(z=540)+C(o.a)*d,9,9),o.d-=q/d;(d<0?-d:d>z)?o.a+=o.d=z:q}
