I'm not talkin' much about our newest release, as of yet, but I wanted to show everyone what Google SketchUp is capable of. I used mostly models from Google Warehouse (they're all completely royalty free), and modified them for what I wanted to do.
I was able to create an entire spy base/lab, as well as two other complex models, using Google SketchUp (free version).
The world map is from a royalty-free map website (I can't remember the link, atm), and the radar screen is from Microsoft Office (again, royalty-free). I build the main screen image using those, and a bit of tweaking in GIMP.
I have since revised this image a little, though I don't have a version to show you (the file is on my work computer, and I'm too lazy to drag it over to this one).
Again, SketchUp is very easy to build with, and requires absolutely no knowledge of 3D modeling. If you can use MS Paint, you can use SketchUp!
