We just posted a sneak peek of Pixate, the new mobile design tool we're building for prototyping complex interactions and animations:
If you've played with Origami or Framer, we're aiming to build something a lot more capable and easy to use—a visual tool that produces real, full-fidelity native prototypes for both iOS and Android.
We're currently in private beta, but we'll have some invite codes for the DN community soon. In the meantime, any input or feedback would be great to hear.
Lastly, if you're attending http://valiocon.com I'll be giving a demo of Pixate there—hope to see you then.
