Galaxy Engine is a complete game development package for Mac, iPhone, and iPad. It is programmed in Cocoa and uses the OpenGL, OpenGL ES, and OpenAL libraries to give you a powerful core with direct access to iPhone SDK features such as Game Center. Galaxy Engine is designed with indie developers in mind. Which means that it is designed to be as efficient and flexible as possible. It also is one of the only Open Source game engines to include critical tools for game development such as: Level Editor, Terrain Editor, Model Viewer, Particle Editor, and Shader IDE. It also includes features such as: vertex animation, advanced lighting, dynamic shadows, vertex and pixel shaders, normal mapping, parallax mapping, and massive outdoor environments.

OpenSource analog of UISegmentedControl. Allows you to customize segment view.

S4LuceneLib is an iOS native version of Apache's Lucene project. The S4LuceneLib directory contains an XCode project that will build an iOS static library for inclusion in your project. The iPhoneLuceneSearch directory contains a sample iPhone application using the library - it is intended for testing purposes at this point.

The S4iOSLib library is designed to be both a platform (framework, if you will) for iOS development, as well as a 'container' for utilities that should be useful to all Apple developers. The library's APIs are designed to convey the same architectural patterns utilized by Apple's iOS/ObjectiveC-based platform. It relies heavily on protocols and delegates, and offers singletons when appropriate for Manager-type classes. The main goal, however, is to provide a robust and stable set of utilities that will allow developers to focus on creating great new features for iOS, and not reinvent the millions of little wheels that underly almost every application.

Hockey is a iOS Ad-Hoc updater framework. It can be used for all apps that target the Apple AppStore and improves the beta testing process dramatically. All beta testers. It consists of two components, a server and a client framework.
The server component is required for all scenarios. But it also can work standalone without the client library. It provides a web interface which beta testers can use to install the latest AdHoc provisioning profile and also the latest beta version via Safari right from the device. One server installation is able to handle multiple applications via different bundle identifiers.
