After some consideration I decided to opensource my 2d OpenGL Java Engine. Hopefully that will make me spend more time on it as I build a game around it and also get some external input. The license I chose was the MIT one. I think it's one of the most liberal licenses out there and I really don't want to prevent anyone from using the engine :)

That said, the project site is hosted @ Google: http://code.google.com/p/oje2d/

I will import the sources into the subversion repository soon but, for now, the current snapshot sources are downloadable here: http://oje2d.googlecode.com/files/oje2d-0.1-SNAPSHOT-sources.zip
