PyGUI is a GUI API which is designed specifically for Python, taking advantage of Python's unique language features and working smoothly with Python's data types on the three major platforms (Unix, Macintosh, and Windows) that are small and lightweight, interposing as little code as possible between the Python application and the platform's underlying GUI facilities, and not bloating the Python installations or applications which use them.
Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.
Khayyam is a program for composing 3D scenes for rendering (similar to Poser and DAZ Studio). It can import character and scene models from many model formats (Poser, MD5, BSP, OBJ, 3DS, Collada, and formats used in most Illusion games). There is support for basic object placement, scaling, posing skeletal characters, and lighting. Scenes can be exported in POV-Ray format for rendering. Khayyam is implemented as a shell program using many libraries from the Floyd and Sodipodi projects.
