@andrew Quartz Composer's Origami offers the ability to export code for iOS, Andriod and Web. Sometimes, the code is a bit messy or has some garbage tags in there, but definitely helps the development team get a good idea of the animations and actions triggered by the interaction with the elements on the screen.
I already love pixate as is, and adding this feature would be an amazing time saver.
Just so you know, building a prototype on Pixate is great for demos, but I end up writing very lengthy documentation similar to this one, shared by Sebastien Gabriel from Google. Therefore, code snippets or exports would be an amazing improvement over my current flow.
Hope this helps!
