    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.

endless urbanscape

Replace v with v%1080 in the fillRect call and it will redraw itself over and over again. ;)
u/DataMeta

Not sure what you mean - it already re-draws. Hence the 'endless' :P
u/zanella

Weird, the first time I saw this it didn't redraw itself - it seemed to stop once the scanline hit the bottom of the canvas. Didn't notice that it already had a %1080. So yeah, my comment is pretty useless. :)
