    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.

u/WorldMerge

This is fantastic! How did you compress your js like that?
u/cantelope

there are a few handy compression tools/dweets @ https://dwitter.net/h/compressor . They don't all work, so look for the ones with a lot of Awesomes, like: https://www.dwitter.net/d/11852 . I've been a long fan and user of Dwitter but my main (and perhaps only) complaint is the strict 140 char rule. It has given me equal measures of inspiration and frustration, hence why I created the spin off site, https://codegolf.tk which has 3 categories, 140b, 512b, and 1024b to allow for more sophisticated demos while still giving credit for the 140b achievement. :)
u/DaSpider

The 140 chars would be better if there were more shortcuts like C(), R(), etc. for functions like Math.random, x.fillStyle, etc.

yes, a free way to fake gloss, it would look better here if the gloss moved too but i ran out of space

ReferenceError: U is not defined
u/KilledByAPixel

how is this possible?
u/tomxor

All loaded iframes are enumerated on the window object (for any webpage), the value is the window object of the corresponding frame... and from inside a dweet this can be accessed (with restrictions) by going to the parent frame, then you have access to any globals in that other frame. While you can't call a function since it's in a different JS context, you can read it's source and re-evaluate it.
u/tomxor

essentually window.parent[n].u is the function created by dwitter for dweet n on the page, if you add it to a string it calls toString which returns the source, you can eval this and assign it to something to run in this context.
u/tomxor

I think I am the most verbose person here sorry :/
u/jellyedwards

Funny idea. On font-size 8em you cannot see the mouths of anyone so I think it works better with 6 or 7.

It works fine with Apple’s emojis. Unfortunately, I don’t have a quick way to test on multiple devices.

I didnt look at your code but I guess you did something like this...

u/aleamb

amazing! love it! #morphing #numbers #blur
u/BriSeven

nearly. i also modulated the blur so the complete crisp numbers would be visible and the morph a bit more metabally
u/BriSeven

i tried to modify this to add it back but i can’t get it under 150
