My 2009 'Christmas Card' to friends and family.
This short clip is made in After Effects using a couple presets: "Distribute", "Sure Target" and "Falloff". Sure Target and Falloff handle the motion between text segments with minimal key-framing and Distribute is very useful for randomly distributing the text in 3D space without spending any time actually moving layers.
I plan on putting together a tutorial for this (or a similar) effect. By using the presets and being careful about your layer management you could animate a few hundred layers of text or images in minutes.
