Made a mixture of a few boot animations for my DROID X.
Stock DROID boot
NeXus Holiday Red
Then added (and mixed horribly) a sound I made from Apple startup, then some stock DROID auido files.
Sorry if its rotated, I forgot about that when I filmed it, but that actual phone and file are in portrait mode. Also, sorry about the "fisheye". My camera is a compact hand held with a 10x zoom. That close, and the lens warped the image a bit.
I have already edited the desc.txt to play one sound at the beginning of the animation. you can use what ever file you want, but it has to be named android.mp3
The sound file needs to be place in the /system/media/ folder, along with the boot animation.
EDIT:: MEGAUPLOAD - The leading online storage and file delivery service Link for the zip with bootanimation, sound file, and the /system/bin/ file.
