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.
golfed but broke: with(x)for(n=c.width|=0,font="19em'",fillText(z='Dwitter',n*C(t),250),fillText(z,n*S(t),1e3),i=2e3;i--;)fillRect(n-99*i+t*n%2e3,460,50,200)
