Wow, I actually saw your Fuji piece earlier but forgot about it! I really like the procedural landscape.
I've done a bit of procedural environment stuff myself, though not much yet:
Spring RainAlso, I'm really excited about groWorld now, Tale of Tales!
I love procedural stuff, and plants, and ecology, and interesting multiplayer experiences and I'm really looking forward to seeing what you come up with. I don't know what you are making exactly, but it reminds of the Jungle episode of Planet Earth - I thought it would be great to make a game where you are a plant competing for sunlight in a clearing opened up by a fallen tree.
Update:
I just saw your blog post
In the beginning... about beginning from the blank screen, the empty void. I really like this because I have thought about this same sort of thing, and its opposite, the white glowing field of possibility.
I wrote more about it
here, on the development blog for my (yet-to-be-created) game
Dejeweled. For Dejeweled (and some other projects) I am using the white glowing field approach.
