    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.

This is the same helix from the previous dweet but now with perspective applied:: X/Z and Y/Z (divided by Z, so the image will get smaller when Z is higher)

This starts with a dual structure for 2 possible values of "r" (random 0 or 1) and then a triple structure appears when r is changed to 3 possible values ( 0 or 1 or 2) #tree
