The elusive Droid Bionic is finally within weeks of release (it should drop September 8th for $299.99), but if you want to pretend you already have one for a moment or if your current boot animation is not a gorgeous fiery bionic eye (is such a thing even possible?), then download this official Droid Bionic boot animation and sound. It won't grow you an extra arm, but it will make you the coolest chap in town (not really).
Update: I've dropped the frames into GIMP and created an animated gif version. It's too big to embed on this page but if you want to see it, click here.
