Command-line utility to transform NIB files for the iPhone into Objective-C code files

Molecules is an application for the iPhone and iPod touch that allows you to view three-dimensional renderings of molecules and manipulate them using your fingers. You can rotate the molecules by moving your finger across the display, zoom in or out by using two-finger pinch gestures, or pan the molecule by moving two fingers across the screen at once. The combination of the iPhone / iPod touch's unique multitouch input system and the built-in OpenGL ES 3D graphics capabilities enable you to feel like you are manipulating the molecules themselves with your fingers.

This ambitious project by AppsAmuck achieved 31 different iPhone applications over the course of a month, each with sample code ready to be downloaded showing how they did it. Although some of the applications are of limited functionality, and the licensing is unclear, overall the diversity of themes and features explored and the demonstration that "you can do it" makes this an inspirational project to check out.
