My new ROM has the animation cooked in. I will try to make a flashable zip for you guys.

I'm not quite sure it will work on an AOSP rom as is uses the .qmg files as opposed to the bootanimation.zip used in AOSP roms.
We're never gonna get it in a bootanimation.zip, simply because the original is in a proprietary format that Samsung owns; meaning it cannot be extracted/ported. I have a zip for the international animation, but it is in .qmg format, and I'm positive that will not work with AOSP roms.
