One popular project is Jonathon Fowler's JFDuke3D, which the original creator of "'Duke Nukem 3D", Ken Silverman, gave support to, in December 2003. Fowler and Silverman produced a new version of JFDuke3D using Polymost, an OpenGL software product for Build, which uses much more advanced 3D models, and 32-bit color. Another project JFDuke3D called xDuke (not related to the xDuke project by icculus.org/duke3d) was created for play on the Xbox.
