Update: The original video is available again at http://www.youtube.com/android
The download is a normal .zip, containing both the portrait and landscape for the size indicated. This is not an update.zip installer. Unzip the two files and copy the one you want to the correct location (usually /data/local or /system/media), then rename to bootanimation.zip (just remove the _port or _land)
Update (10/27/2011): Added sound to all versions. You need to re-download and re-install the animation, and download the additional sound file and move to proper location. The location is usually /system/media or /system/media/audio/notifications. Some devices/ROMs have a different location, search the forums for your ROM and you should be able to find out.
Update (10/21/2011): Added tablet versions from JaeKar99. Added shortened versions (4 sec shorter) for devices that boot too fast to finish the animation. Added MTZ version for MIUI themes (480 only)Update (10/20/2011): Looping ending added. Previews not updated. Hi-res tablet version and shortened version coming tomorrow.
