I chose a map of Europe. When the cursor went over a city, music started to play that country's national anthem. It was too much though - a little distorted and loud. Clicking on the London icon brought up the London window. A brief history of London appears with a map.
Red icons pop up on the right side of the window, which allow for viewing of the major highlights.
Diving into the subways of London, the viewer is offered a few choices for beginning points. Move the mouse over an icon, and an explanation of what the icon is pops up. The next window was well done. The top portion of the window was a frame for playing QuickTime Virtual movies of the cities highlights.
