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.
different belt: for(c.width|=1,k=(1-T(t))*99,i=2e3;i--;)i<9?x[r](i*99+T(t)*300,400+(-1)**i*k*(k>0),50,200):x[r='fillRect'](i,300,.3*((t*3e3-i)%99<4)+.1,400)
messing with tan in the default is actually how I came up with the idea in the first place. nice remix!
