    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.

weird spiral, made by ChatGPT

u/cantelope

correction: made by humans whose hard work was de-ownerizerd and obfuscated via chatGPT's convolutional neural network. the output of data-driven systems be they "generative" or not, by definition, are functions of and may not exceed the quality of their input
