The Space 1889 Planet Project

Clockwork Publishing (or Uhrwerk Verlag, properly) is working on an interesting project.

Space: 1889 is a steampunk role-playing game taking place in a fictional Victorian era of earth. Using steam-powered spaceships, human explorers flew through the ether and colonized Mars, Venus and Mercury.
Under patronage of DereGlobus, our fan project aims to visualize the populated planets as interactive atlases in Google Earth.

Here's the link (in English) for more information.
