Apple's Quartz Composer has enjoyed renewed enthusiasm as a prototyping tool after recent news and video tutorials on how Facebook prototyped Home using the tool.
Joris Kluivers takes QC-based prototyping for iOS one step further with qc-mobile, which makes it possible to load, display, and interact with
.qtz files on iOS.
It's still early days for the project (as Joris explains in his introductory blog post), but it is functional enough to render Jay Thrash's iMessage recreation as seen in the demo video below.
Now is a great time to get involved and make significant contributions to the project! qc-mobile is MIT licensed and hosted on GitHub.
