    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.

Type stuff! No newline support, unfortunately. :'(

u/Jenky

Also no insert-style editing, only way to erase is backspace. Old-school terminal/console style. 😎

lol... where are my Wordstar keyboard shortcuts

I love it that backspace works!
