    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/lewdev

Thanks u/cantelope but credit definitely goes to u/KilledByAPixel for making "Tiny Starfield" so tiny (93b)!
u/lewdev

I found a similar amazing use of onmousemove with d/24231 by u/Joachim
u/magna

You can avoid having to initialize X and Y by hijacking existing globals you don't use like T and R.
u/lewdev

Great tip u/magna! I was thinking about that a lot to cut out bytes recently.
