I started messing around with a little program called FlowScape the other day, and found it rather fun to work on forest and landscaping scenes.
I understand it should have object importers, so I can get an inappropriate mix of tech and nature going, but until then, I'm working on this.
I almost want to write a little thing for this, a foggy forest where under the cover of trees and skies, a riverbank is used for illicit deals.
I wanted more light pollution to blot out the stars, but hadn't quite figured out how to get that effect in this app, because this forest is part of a natural city border, and the cities are very much broad sources of light pollution in the age this falls in.
I'm basically tempted to get back into writing Chronoverse shorts, where this is a Middle Sphere planet. Just enough of a blend of magic and technology to make both aspects dangerous, basically.
