A while back I discussed the advantages of a flat version of Google earth inspired by the movie clip above. You can do it via the Maps API for flash but that requires technical knowledge. A much easier way to do it is to put a world map in Google Earth as an overlay and add placemarks and loops (loops howto). I recently did this for a client, here's a stripped down version
Better than Screen Overlay: It makes for a better presentation than a screen overlay because you can add any sort of element above the ground overlay including loops, placemarks (as I've done here) and even other screen overlays.
Flat Map with Tours: One of the good things about this idea is that you can present a flat overview with 3D features like loops or Sketchup Models and in a tour, fly from the flat map out to the globe and zoom in on a particular country. So you could start with a thematic map showing how much individual countries were donating to Haiti then switch back out to the 'real' Google Earth and fly in on Haiti itself to see how the money was being spent.
Tip for the KML Savvy: You could even edit the flyto tag speed to be a fraction of a second, this would take the viewer from the flat map to a high view above the country without them even being aware that they've moved between transitions.
