This is a port of Pixel City by Shamus Young converted to Mac OS X. The original Pixel City project index is at http://www.shamusyoung.com/twentysidedtale/?page_id=16458.
This project can build a stand-alone application or a screensaver (or both). Select the target from the Xcode window to choose which to build. The application contains more settings and effects than the screensaver; some of these are for debugging and some are experimental and haven’t been ported across yet.
You can install the screensaver by double-clicking on the .scr file.
This screensaver uses old-style OpenGL calls (i.e. pre-1.5) and no shaders. I intend to modify it to use shaders as a learning exercise later on.
I have exposed some of the screensaver settings as options, shown below:
I have also added some fog settings, including colour-cycling the fog settings.
