    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.

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

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

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

#interactive #quadtree (move your mouse)

u/tomxor

Note the intersection is fuzzy since full circle-AABB takes too much code, instead it's just circle-point + current subdivision width based radius (w*w*6.28), i.e it becomes more accurate as it converges.
u/tomxor

This is why there are a bunch of divisions around it that would not exist with an exact test. Pavel's doesn't do this by cleverly choosing a geometry that only need intersect the top left of each square.
u/katkip

Nice!
