The first firts free .aep project file using the New FreeForm AE is up on the Mettle website.
See:

Many users in the past have asked if this kind of effect is possible - here you go :)
You will need AE CS4 and the latest version of FreeForm AE to run this project file.
Enjoy. I will put up more when time permits.
Cheers,
