    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.

Each line segment can have 16 directions (4 bits). The 100 line segments are encoded in 25 UTF-16 characters. Very ego-centric result, i know, i know :)

play with x.fillStyle;-)

u/lowpoly

For example, x.fillStyle=Math.random()>0.5?'#000':'#fff'
u/lowpoly

or x.fillStyle=(~~(i/s/s)%2)^(~~(t*s)%2)?'#000':'#fff'
u/sigveseb

So intense colors!
