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.
Erm, with all the requisite quotes and stuff: c.width+=0; x[f="fillRect"](0,540,50,p=100); x[f](30,565,p,50); x[f](a=((t*6e3|0)+((1+S(t))*5e3))%1920,585,10,10); x[f](a<(e=960)?e:a,y=490,20,200); x[f](e,a/3-p>y?y:a/3-p,20,200);
