SourceForge, described as the most prominent repository of open source software, selects an outstanding contribution to recognize on its Project of the Month Web site. As with all open source projects, the software can be freely downloaded, used, and modified. Examples of past projects of the month include an instant messaging client, a 3D game developing kit, and a tool for porting applications from UNIX to the Macintosh OS X operating system. A description of the project and an interview with the project's creator showcase the software.
