Origami – Design Prototyping
AFAICT Origami is still a collection of plugins for Quartz Composer, a graphics tool by Apple that's included with Xcode.<p>Quartz Composer is effectively deprecated: no updates since 2011, not available in iOS, no Retina support. Building new products on it is not a viable long-term solution, so I wonder if Facebook plans to build a replacement.<p>(Incidentally, if someone wants to make a new Quartz Composer work-a-like, I have a bunch of potentially suitable code that I could share with an open source license... I made a node-based graphics app called PixelConduit whose code I was planning to release but never got around to: <a href="http://pixelconduit.com" rel="nofollow">http://pixelconduit.com</a> -- it could make a solid base for a QC-style tool.)
