    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.

I feel like I've seen this before, but I'm not sure where
u/taupelink

The "*6.28" can be omitted...I had had Math.random in place of T, but it didn't fit

Random number distribution

u/username

seems flawed
u/veubeke

Because it’s showing the last 480 numbers. If you accumulate more data it eventually evens out.
u/joeytwiddle

#random numbers are more likely to coincide than fall evenly. Coincidences are almost guaranteed! https://en.wikipedia.org/wiki/Birthday_probl…
