    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.

Hello. I want to use this code in my future game as generator of the part of the background. Also I would try to modify it slightly so generation would be partially random and big "skyscrapers" will have more details (2-color grid representing windows)
