TwUI — Core Animation UI Framework for Mac

New open-source framework from Twitter engineers Loren Brichter and Ben Sandofsky:

TwUI brings the philosophy of UIKit to the desktop. It is built on top of Core Animation, and it borrows interaction ideas from AppKit. It allows for all the things Mac users expect, including drag & drop, mouse events, tooltips, Mac-like text selection, and so on. And, since TwUI isn’t bound by the constraints of an existing API, developers can experiment with new features like block-based drawRect and layout.
