    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.

Aye, that implied double-helix in the movement is pretty cool.

I like how if you stare at it long enough, you see shifting concave diamonds. Very cool!

another 4 bytes can be shaved but it will take longer to draw ;-)

62 bytes, same speed : x.fillText(x.drawImage(c,(V=t*9%3|0)*480,V%2*540,960,540),9,9)
