    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.

my TP stash !

u/pavel

To get (X,Y) out of n you do (n%width,n/width|0). Here n=60*t and you got 21 TPs across so x.font='90px"';x.fillText('🧻',60*t%21*90,(60*t/21|0)*90)
u/pavel

This reveals that if we pick n=63*t we can shorten Y=63*t/21|0=3*t|0
u/Odog8

Thanks!

u/DaSpider

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

Wow that's amazing!
