    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.

Wow, it looks so amazing. Like its real/nature. Very cool!
u/vain

Where did you get all your inspirations and algos from? ;-)
u/rodrigo.siqueira

The "infinity" symbol is just the graph of: X=sin(i/2) , Y=sin(i). A particular case of #Lissajous curve. I then introduced some noise and interference It emerged as a remix of previous posts.
