    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 a template to play with drop-in replacements for Math.random(). Enter code in the last line that uses the existing variables to produce values in the range [0,1). Red squares will appear if values are out of range.

Nice alternative to perlin noise!

Very nice! And with the horizontal flat line we can pretend that is the sea level; everything above is a mountain and everything below is the sea :)
