Arctic Kerbonaut

Here are some things I could think of at the top of my head: I would love to see footsteps and wheel tracks, especially on sandy planets and moons like the Mun or Duna. Ocean waves would be nice as well. Steep cliffs and canyons. (That one's pretty much confirmed) Changing weather and different climate regions. Flowing lava and possibly even active volcanos.

I'd love to see a show and tell focusing on the music of the game. As a musician, I'd love to get some insight into the process of creating the soundtrack to a game like this.
