    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.

#d3 #perspective #cube #remix -- this alternative approach is more "correct" in drawing each cube once (and avoiding the moveTo/lineTo dance), but it actually loses the multiple-stroke effect that makes the outer cubes heavier
