Why does everyone build these on top of Quartz Composer? It seems like there's a huge demand for a prototyping tool that supports animations.

Here is an interesting prototyping app which does exactly that. Downloaded the beta and playing with it. http://www.mitya-app.com/

Axure is able to illustrate quite a few animations, although it could certainly stand to include more. I'm hoping they'll make this a priority in future releases.

I'm just hoping Apple offers up a new release of Quartz Composer which incorporates the Origami patches and fixes a few more bugs. Speeding up live renders would be a bonus, and I'd cry tears of joy if they figured out a way to openly release their internal Core Animation prototyping tools.
