nib2objc has been featured recently in The Changelog, a blog about open source projects:
Interface Builder is one of the coolest things about Cocoa development. Being able to draw your interfaces visually can save you tons of otherwise tedious code to create layouts and set visual styles for your user interface elements.
Adrian Kosmaczewski, iPhone and iPad developer and creator of Device DNA and several other apps in the App Store turned us on to nib2objc, which is a brilliant name because it takes NIB (or XIB) files from Interface Builder and converts them to Objective-C.
