This does grab my attention. We're in the middle of polishing off wireframes and beginning design work on our startup. Since we are still in the process of finding a developer to join, we're looking for software to help us prototype wise. The UI capabilities with Origami seem tempting. We we're looking at Proto.io and Invision. Any thoughts?
I've been looking at something like this to pick up. Didn't know that this was released until today, but there seems to be a lot of people who are using http://framerjs.com/. Seems like the FB team was using Framer until they developed their own. Check the Product Hunt post: https://www.producthunt.com/posts/framer
