    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.

Reminds me of a scene from Intrinsic Gravity. I actually want to do a Dwitter demake of the entire demo, using multiple dweets stitched together. Made a few screens as separate dweets a while back.

AMAZING! Btw, you can save 3 bytes without changing the visuals or camera path by using fillRect(i,j++,2,~h) ;)
u/jylikangas

Thanks all! p01 - I didn't know fillRect takes negative height. That's gonna save bytes in my other demos too - big thanks for the tip!
