Nokia Maps API supported web browser (basically any modern browser should do).
Example code
This example will start panning the map to the right, then after a moment changes direction to the left and continues forever(?) ;) Unless you stop it by pressing the button and clearing the timer and interval settings.

Summary
Using the map panning feature you could create e.g. a game, where the map is moving and the user should e.g. find something on the map and click it before the area vanishes from sight, just an idea ;) develop your own =)? Side scrolling game...? =)
