You should check out this site. Great for motion graphics, and all of their “animated typefaces” are built in After Effects. I embeded the video for you guys below Fast Company’s blurb.
Are animated fonts the future of type?
Animography is a collection of animated typefaces by Jeroen Krielaars that can be licensed as you would any other. And while we all have our stereotypes of what animated text can be—local commercials of monster truck rallies come to mind—they’re a far cry from the hokey flaming letters of LiveType. Instead, Krielaars has constructed what might be called “classic” animated glyphs for words that could look as professional in print as they do in video.
