    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.

procedural javscript gibberish generator #ai

u/timothytomato

change the string in a=this.a||'dwitt' to something else for different gibberish. it works by comparing the current character with document.body.innerHTML and predicting what the next character should be, so kind of like a really bad autocomplete.
