    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.

This is an attempt at a byte packing algorithm, which packages two bytes into a single JS character.

It works, but it's footprint is too large to work in 140 characters. The algorithm itself is 75 characters, we need sub 70 characters to make a character profit.
u/MrOpposite

Feel free to remix if you figure something out that can reduce it even further

Hello sir ! As a matter of fact, we can :) during the past years @subzey, @fakeunicode and I (@MaximeEuziere) have built a solution allowing to store 194 ascii js chars in 140 characters, including the unpacking and the eval. The decoder is 43b long. All the details are here: http://xem.github.io/obfuscatweet/. Cheers
u/MrOpposite

@xem Actually, those are encoded as "multicharacter"-characters. I only work with UTF-16, and thus fit 2 bytes into a single character without making <string>.length "see" my extra characters.
u/MrOpposite

<string>.length *
u/xem

Ah okay. Here's a version 1b shorter: eval('挮睩摴栽ㄹ㈰㭦潲⡩㴰㭩㰹㭩⬫⥸⹦楬汒散琨㐰〫椪㄰〫匨琩⨳〰ⰴ〰ⰵ〬㈰〩'.replace(/./g,a=>String.fromCharCode((p=a.charCodeAt())>>8,p&255)))

Slideshow v2.1: A minor bug fix. Previous versions no longer work because of dwitter improvements. Good news is we can now use }{ in dweets for one time code.

u/AnnanFay

See https://github.com/lionleaf/dwitter/issues/2… for details on the improvement.
