Unlike Picasa, however, which runs with its own bundled copy of WINE, an open-source implementation of the Windows API (application programming interface), Google Earth is a native Linux application.

The free-for-personal-use Google Earth is more than just an incredibly neat toy, though.

That said, its also a really great toy.
