Google Earth puts a planet’s worth of imagery and other geographic information right on your desktop. View exotic locales like Maui and Paris as well as points of interest such as local restaurants, hospitals, schools, and more.

I wouldn’t go so far as to call Paris exotic, but it really is a pretty fantastic piece of software. It’s free, but unfortunately Windows only (no linux or osx clients, grrr).
