    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.

u/lewdev

what was the prompt?
u/cantelope

i think these push button, AI dweets are no different than posting someone else's work. Even if they tended to be interesting, it would be questionable. I'm going to recommend that the platform ban this stuff
