Google Earth

I was very happy to discover that Google Earth finally has a Macintosh version, and I've been happily playing with it. I first went to my favorite place - Jerusalem - and discovered that the resolution isn't very good (it's much better for Manhattan, for example). However, enterprising individuals have put a much more detailed overlay of the Old City, which makes it easier to identify individual sites in the city, for example the Church of the Holy Sepulchre or the Temple Mount. As I imagine many people have, I spent some time looking at lower Manhattan, at the site where the World Trade Center once stood - many people have provided overlays for the site, including a fairly detailed timeline of the September 11, 2001 attacks. I also looked at Baghdad, where some energetic soul has pinpointed the locations of many of the deaths in the Iraq War. It's really an amazing resource, as well as being quite a time-sink....
