IMVU has benefited greatly from open source software. Large components of our client and website are built on top of various open source projects. In fact, you can see the list of software on our technology page.
Well, I'm happy to announce that we're beginning to contribute source code back! We have created a project on SourceForge and released our first standalone tool: pstats_viewer.py. pstats_viewer is a tool for browsing the data stored in a .pstats file generated by the Python profiler.
