    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.

thank you for cleaning up my idea ;) your solution is very neat

Thanks :) It lacks the yellow color, though. I'm not sure I could hack that in without removing the rectangles

Golfed a bit (128 characters): i=W=c.width=960;x.lineWidth=80;x.arc(X=250*t%W,200,40,G=.3-.3*S(X/29),6.29-G);x.stroke();for(;i>X;i-=190)x.fillRect(i,190,20,20)
