    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.

this is clever af

How is it a neural network? You're just drawing random squares on a cat emoji :P
u/pythech

whoosh
u/magna

Yeah, sorry, it was a bad joke. Just transferring random rectangles from an off-screen canvas. The only catch is the use of valueOf to cut down on the function call ()s.
u/iverjo

Clever indeed!

If you wait long enough on macOS, it starts looking like you've zoomed into a gold-plated torus.
