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.
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.)
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).
