You can play the whole tour as a slideshow, starting from the beginning to the end. To start this, click 'Present'.

If you prefer to look at each day in isolation, you can do this as well. Click the day you would like to look at.

To the bottom right of the main screen, there are tools you could use to further investigate a picture, a map etc. The top right button above the globe flies you to your current location. The person (or 'Peg Man' as it's called) allows you to drop into a street or scene. To do this drag the Peg Man out of the circle and you should see blue lines or blue dots. Drop the 'Peg Man' on a part of the blue line/dot you're interested in looking at. 3D/2D button gives that view of the scene. The red/white button gives you a north/south view of the scene. If you double click, it swaps with the globe.
