Letter-by-letter Text Animation?

I’m just wondering if it’s possible to animate text animations like in this video: https://vimeo.com/39782582, where the letters expand one by one to build a word. Is there any way to do this without breaking each word into a bunch of individual 1-letter text objects and animating them manually with a time offset? How to do the typewriter effect would also be nice.

Thanks! That addon is quite crashy…though it works!
