About PixelCity OSX:

When I stumbled upon Shamus pixelcity project on google code I just had to port it. :) Turned out it wasn't all that difficult, so here you have it! Source is included in the distribution.

• There are no art assets. All content is generated at runtime.
• Written in C++ using OpenGL. No fragment or vertex shaders are used.

The original project and code by Shamus Young can be found here.
