    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.

u/Joachim

Wow. This is very clever
u/rodrigo.siqueira

Now I can't look at city buildings without thinking about this. See https://en.wikipedia.org/wiki/Tetris_effect The Tetris effect (also known as Tetris syndrome) occurs when people devote so much time and attention to an activity that it begins to pattern their thoughts, mental images, and dreams. E.g. People who have played Tetris for a prolonged amount of time can find themselves thinking about ways different shapes in the real world can fit together, such as buildings on a street.

Nice idea! As an added bonus, if you leave it running for a while you get a graph of the prng bias for free :)

I remember on some devices, fonts over a certain size just don't show. A workaround is to use a scale transform, or reduce the canvas size.
