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.
if you want 'correct' scroll direction: w=c.width=400,x.fillRect(0,0,w,w),x.fillStyle=R(0,w) for(Y=32;Y--;)for(X=44;X--;)x.fillText(String.fromCharCode(0x30a2+(t*X+Y)%90),X*9,280-Y*9)
