    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/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!
