    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.

I was attempting to optimize for FPS, try commenting out the var line

Kudos to anyone, who can modify this to show something slightly more interesting. C(9*i++) is the Y function.

u/lionleaf

Changing to 99*i makes it a cylinder! d/7275
u/prplz

Different cylinder and modified loop d/7279
u/BirdsTweetCodersDweet

9*i makes a cylinder too
u/BirdsTweetCodersDweet

for(c.width+=i=0;i<d;){X=S(9*i) Z=C(99*i) is cool
u/BirdsTweetCodersDweet

d=1e3 for(c.width+=i=0;i<d;){X=S(9*i) Z=C(99*i) B=(4-Z*T(t)+X*S(t))/d x.fillRect(d+(X*C(t)+Z*S(t))/B,d+C(9*i++)/B,.03/B,.03/B)} is even better

Oh, why do you use kanji characters as variables?
u/AnnanFay

The kanji are so I don't accidentally redefine a variable which something uses. For example there's code which does t||(_=c.width) so if I use _ it would break the code. It will break stuff which uses these kanji, but right now this is the only dweet using them.
u/fujimotos

Nice. I didn't know that they are valid variable names...

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

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!
