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.
Here is the #uncompressed version (139 chars): for(c.width=X=128;X--;)for(Y=72;Y--;x.fillRect(X,Y,h*10/d,1))for(d=9;d++<X^(h=(Z=d*(X-64)+S(t)*200>>5)&Z<9&Z>-10&(y=d*(Y-36)>>5)<3&y>-3);)1
