Hi,
As you may now in UK for instance, you can use google map and
use your arrow key (up,down,right,left) to travel in the country.
You simply drag the "little yellow person" to a given location on the map, and then, it starts.
What about a Linux dedicated software that would allow you to travel in a quake like environment?
regards
