I was enjoying a Google Earth video earlier today and it got me thinking. What kinds of new things will become of this kind of software? With the new availability of 3d building and rendering software in a short period of time we will have built a virtual world quite literally. You'll be asking yourself.... "Is it real, or is it Memorex?" But seriously, we're well on our way to world tourism at your desk. As the video demonstrates, the possibilities just for architecture are huge. You can build you house and see it in 3d inside and out before the foundation is laid. Just last week I found a website that will let you track a commercial flight in Google Earth, in near real time.
