E-Cell System is an object-oriented software suite for modelling, simulation, and analysis of large scale complex systems such as biological cells. It allows many components, driven by multiple algorithms with different timescales, to coexist. The core library is written in C++ with a Python binding, and frontend software uses Python.
MapIt! is a simple Web-mapping application implemented in Python that lets you navigate raster maps through your Web browser. It lets you zoom in and out, and select objects and object classes that are highlighted on the map. MapIt! can be integrated with an existing Web server in several ways: as a CGI script, Fast-CGI, or in Apache with mod_python. It can also serve GIS results over the Web.
