My report is somewhere on the world wide web, maybe Google Translate can give you a first translation:
http://membres.lycos.fr/javalution/download/gimballock.zip

I had weaker math knowledge when I wrote it but I did my best.

It's not reasonable within a real framework of animation, that's why Ardor3D has a simple fix for singularities and this engine is used by the NASA. The problem is that when a student reads your lesson, he might think that you provide a general solution to work around gimbal lock whereas you only put yourself into a case far from singularities, these are 2 different things. Of course, your "framework" is enough in some cases but in my humble opinion you should write something clear about this limitation to avoid confusion.
