    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.

Diet Sinewave Pattern, now with only 108 characters! (Had some leftovers from my original dweet idea that were clogging up the charcount, plus optimized the loops and positioning)

98 chars: for(c.width|=y=40;y--;x.fill(),x.beginPath())for(w=33;w--;x.lineTo(60*w,S(t+y/5+w/2)*50+30*y-75));
u/firegodjr

Thanks! I'm a bit new to reverse loop iteration, so I didn't think of replacing the --w+1. How does the c.width|=y reset the width properly, though?
u/BalintCsala

It sets it to 1960
u/iverjo

Cool! Deserves more attention

Ah, u/BalintCsala beat me to it... :)
u/jylikangas

96 chars if you replace --w+1 with w--

Why does deleting the code still let it work? is it overriding the contents of u()?
u/BuRRak

what the fuck
u/BuRRak

This still blows my mind and i don't understand it at all
u/BuRRak

Oh, it makes sense now, you are using invalid characters that are not visible. Very clever!

u/ZerataX

yeah after the location is set once, it doesn't matter if you remove the code. more or less just letter substitution: https://jsfiddle.net/Lcjo35h4/1/
u/ZerataX

btw those are Hangul Fillers and Variation Selectors. since they are all supposed to be applied to other characters they don't show up on their own.

I think this site should be a bit more restrictive about such practices :p

u/magna

Super cheating. But I don't care. Playing as we speak.
u/lionleaf

Yeah, this dweet might stop working at some point in the future :P But all in good fun for now
u/Galaxtone

This is just a cheat, If you run the code without the eval it just reveals document.location="//media.tojicode.com…bsp/";

This is pretty funny though. Obviously disqualified, but still “valid”.

works after hovering it

u/h3rmanj

probably don't work in older browsers either
u/BirdsTweetCodersDweet

It doesn't work till you hover on it, because v and y have no default values
u/BirdsTweetCodersDweet

c.width=568 t?0:(v=0,y=0) c.onmousemove=e=>{v=e.x,y=e.y} x.beginPath() for(i=88;i--;x.moveTo(300+S(t+i)*200,150+C(t)*C(i)*150),x.lineTo(v,y)) x.stroke() is too long, but fixes the hover issue - maybe you can golf it ;)
