    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.

Here is my attempt to render the world in 3D.

This is based on d/5423 and the amazing bitmap renderer d/5233 by u/RomanW.

This earth is backwards! I think you want S(t+i) and C(t+i)
