    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.

With help from the code golf team, we were able to get the matrix crawl to have a black background :D

u/sigveseb

would be cool to have some sort of feature in dwitter to group effects into categories. Here's my take at matrix! :D d/4922

Tags would be helpful for grouping effects
