Development is going well... in fact we've added a new part-time member to the team who's consulting on climate and atmospheric simulations.
And we've finally got the internal database of objects (planets, moons, galaxies) working and Eric, our astronomer, has been building up its contents.
We've also been working on merging our new procedural planet system with texture based planets which will allow for some really cool demonstrations on the surfaces of planets.
I'll share some screenshots once we're a little further along and are sure that we'll be shipping our latest experiments. I don't want to promise a feature that we ultimately decide isn't going to work...
