XAML Genie Animation Effect

What XAML would you like to create a Genie animation effect? Take an object of any size / shape, and "Genie" to another minimized location. The view is like an OSX window is minimized. Maybe even a slightly whimsical smoke effect where the path switches back more than a simple funnel (if that makes sense).

I am guessing that there is some kind of Path that could be drawn, and the shape could move and transform along this path. Just a wild guess.

Thanks for your ideas.
