Although I've never had to make kinetic type, the limited animations I've had to create for uni were trouble enough so I think I'll stay on the outside looking in for a while yet. (not to mention watching viscom kids' pain in After Effects...)
This is probably one of the most intricate examples I've seen; it's really quite amazing. What's more amazing is that while Jarret Heather (the creator) has been making websites for several years, this is his first foray into animation. I'd call this one a must see for type nerds.
