    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.

pixelly is better than fuzzy any day!

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!

118 byte version including Mathieu's tip... for(c.width=i=W=199;i--;)for(j=9;j<W;x.fillRect(i,j++,2,~h))x.fillStyle=R(h=((d=W*4/j)*S(A=i/W)&d*C(A)+t)*99/d,j,h||W)

I was hoping for a more interesting vertical path but couldn't find enough bytes.

S(G+t) saves a character.

Thanks - that was left over from a previous optimisation for computing a different Y offset
