First update Marble to latest master and get the bestofosm4.kml file inside:

http://www.google-melange.com/gci/task/view/google/gci2014/5240301912326144

and follow the first 10 places in the Tour Panel player. The whole idea is to create a new tour which presents places in the same way - just for your favorite map theme instead.

Now be Stephen Spielberg and direct a Tour about your favorite map theme. Tell the whole story:

- Create a similar Tour for your favorite map theme (OSM and the Moon map theme are excluded for this task - so please choose a different one).

  - Add 10 FlyTos with appropriate Waits and flight durations in between

  - Make a balloon pop up for each place that displays text and images similar to the bestofosm4.kml . Add some text with interesting facts about the place you show.

  - If there is an opportunity then add soundcues.

The whole thing should be entertaining, interesting and nice to watch :-)

Save the whole tour as a kml file (save the images you use in the same directory before you add them) and attach the resulting tarball to this task.
