I now worked on several Levels. I think I had some good idears which I realized now. I will post some screens as soon as possible.

I also worked on some shaders:

Unfortunatly I "only" have A6 Com so the glass is realized with a env-map and not with render to texture. So particles for example are not shown when you look through the orb.
