If you search for "kinetic type" on Vimeo or YouTube, you'll essentially find video with animated text. They vary in quality from flat and simple, to those like this one. Above and beyond the fact I'm a Rage Against the Machine fan, this is an incredible video that could easily stand in it's own right as an official music video. The power of words compels me!
A little mashup I made from the Creative Commons copyright-free Prelinger Archive at archive.org and some Rage Against the Machine. There's something to be said about a good juxtaposition: kickass music and mass destruction.
EDIT: Thanks to YouTube's copyright snitch algorithms, this video is not viewable in Germany. May I suggest my German friends watch this instead.
