    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.

A take on matrix effect.

u/larzuk

i thought "A take on" was meaning "a try at". Don't know what this title actually means. Sry X|
u/Jasper

Your title makes sense, don't worry! "My take on the Matrix effect" means exactly what you meant :)
u/larzuk

Perfet, thanks :)
