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

    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.

Welcome to the dwitter family!

Nice style!

Here's some quick golfing down to 68: p=7*t**3;A=3e3/p**.2;x.fillRect(960+S(t)*A,540+C(t)*A,9*S(p),9*C(p))

A=3e3/(t**3)**.2;x.fillRect(990+S(t)*A,520+C(t)*A,9*S(A),9*C(A))

Thanks, u/Xen and u/magna! Of the two suggestions, I'll have to side with u/Magna's for golfing it down while maintaining the glitchy-ness!
