    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.

Very nice! Where is the sprie from? For some reason it feels really familiar…

u/Bugsy

While it’s doable, yes, it goes against the intent of Dwitter. Dwitter is fun because of the limits put on your code. Without that, it’s just ordinary coding. While I applaud your curiosity and experimentation, I really hope you don’t do this in the future. It really defeats the purpose/goes against the spirit of what we’re doing here
u/FFS2309

I kinda guessed so, this was actually more an experiment about the possibility of achieving external script loading in 140 chars

Beware #gpt3 will take our jobs as dwitter golfers... Prompt to ChatGPT: "Write a small js code golf that draws something interesting on canvas". Answer: "Here's a code golf that draws a spiral on an HTML canvas" (followed by JS code with explanations). I did minimal interference (to fit center screen, changed "j<4" from the original code to "j<9" to improve contrast, changed c.getContext to x.)

u/Qwitter

Robots are our friends. And do you get paid???
u/rodrigo.siqueira

I don't get paid... in fact I'm paying to use the GPT-3 API (because the free version is too politically correct and moralistic). Some artists are complaining about the image-generating AIs, but I think those image generators are helping to spread the names of unknown artists (they are used as prompt modifiers to define the resulting style).
u/tomxor

Yes but what was it derived from, GPT is very good at lying.
u/Odog8

Lol where do you think the dataset came from
