Variant where the distance scale factor… by taupelink

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

} // 122/140

    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.

Variant where the distance scale factor is 1/2 plus-or-minus a little bit. Also some code golfing

I think some of the pattern details are an artifact of the way I golfed the code...of whatever the values of sin(i*540 radians) are, for integers i=0,...,539
