    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.

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

Updated with better colours and way to change the speed, standard of .5; still counts weird but that's okay
