This is a video where you can see:

- YoFrankie - an open game project by Blender Institute - yofrankie.org

- a horizontal Dome - this dome is a test dome, installed at SAT - la société des arts technologiques - sat.qc.ca/

- Blender Game Engine - an open source game engine being used to display realtime content in the dome. blender.org

I'm working in the implementation of a dome mode in the Blender Game Engine. So far it's working pretty well.
It's most likely that this will be integrated with the "official" Blender in the future.
