    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.

Always a bit longer in JS than on the Commodore.
u/loktar

If not for having to scale to make it viewable it can actually be smaller, removing scale and doing 2e3, vs 750 produces a nice result fullscreen.

#maze wow, some amazing implementations I'm glad I didn't check prior lol.
u/andrea270872

I learned programming with a C64! Ah, the nostalgia :)
u/loktar

@andrea270872 same here actually, although I've accumulated many more Commodores and various models since then haha

I just learned about that book today, through a different channel
