A new version of the Minas Tirith model viewer is available here.
Note that due to bandwidth problems, we have decided to split the viewer into 2 versions: a private (complete) version, and a public one. You can only download the public one on the website. The screenshot above is from the private version (which is approximately 2 times more detailed). The polycount averages 4 millions now.
PS - will your procedural universe engine be open source?
