"MakeHuman(TM) is an open source (so it's completely free), innovative and professional software for the modelling of 3-Dimensional humanoid characters. Features that make this software unique include a new, highly intuitive GUI and a high quality mesh, optimized to work in subdivision surface mode (for example, Zbrush). Using MakeHuman, a photorealistic character can be modeled in less than 2 minutes; MakeHuman is released under an Open Source Licence (GPL3.0) , and is available for Windows, Mac OS X and Linux.
The MakeHuman 0.9.1 Release Candidate was published in December 2007, prompting considerable community feedback. Development effort is currently focused on the 1.0 Release, based on a new GUI and a 4th generation mesh. This release also incorporates considerable changes to the code base which now uses a small, efficient core application written in C, with most of the user functionality being implemented in Python. Because Python is an interpreted scripting language, this means that a wide range of scripts, plugins and utilities can be added without needing to rebuild the application."
