Google Earth!

[Will]

Has anyone else tried this? It runs pretty shakily for me, as my computer is an editing system rather then a graphics engine. But it still work pretty well, and it's absolutely fascinating zooming in and out to almost anywhere in the planet!

I've already found at least three remote islands I want to visit. :)

Installed Google Earth some time ago but think either the graphics or video card can't deal with it and so never got it to run properly.

It's pretty good, but an overrated experience in my opinion :D I have a similar program that covers space called Celestia. It can be downloaded HERE (http://www.shatters.net/celestia/download.html)
