Kinetic Typography. I really can’t get enough of this stuff. It really is wonderful to watch and it’s really is just so impressive what can be done with just text. Here is a collection of some of the best ones I’ve come across over the past 2 weeks or so.
And this guy combines the typography with real footage to really cool effect.
This dude is kind enough to explain how it’s done.

And here is another Tutorial over at AE Tuts aswell that I was made aware of thanks to Sean O’ Grady
Anyone have any better ones to show off or link to? I’m gonna try my hand at this over the summer. It can’t be that hard, riiiiiight? 
Yeah, I’m a big fan of the tut+ sites. There are no tutorials on the typography aspect on AE tuts though which I thought was unfortunate. Or maybe I didn’t look properly
Thanks for the comment!
http://aetuts.com has some very nice tutorials. It’s fairly easy to pick up too..
