Spaceport Exo revived

As long as I breathe, I wont give up on my child project! Spaceport Exo has been reincarnated many times on many different platforms and visualisations. I think this is the best attempt so far on Android. Although the 2D version I did earlier this year advanced pretty far as well, the new 3D approach works rather smooth and feels quite natural. In the screenshot here are different shaders at work: multitexturing on the terrain, skycube, and default phong shading all combined with distance fog to make seamless transition into the skycube backdrop. There is a day-night cycle on the fog, but this is not yet implemented on the models.
