Presentation and image sequence ?

Is it possible to set up presentation in BGE like>

  1. there is still background image
  2. presentor can control rotatable 3D sphere which can activate new image sequence on particular part of the background
  1. yes, add a background scene, and do what you like there.
  2. yes, but you need a tiny bit python for it, or make a wire mess with bricks.

2.a: put image on a plane call it whenever you need it.
2.b: this is where .a comes in, you need something that tells you how much the sphere rotated and with those details you show/animate the image/plane to get into the camera sight.
