Lovely. Looking forward to seeing it in-place.

I use the slope of the terrain to guide the wind and use a height map to make sure the wind is never at an altitude that is below ground level. If I decrease the speed of the wind to a small amount, it putters along and eventually gathers in depressions so I could probably use the same code to make objects that move on the ground. Like bunnies or giant mechanical spiders.

Nice! I worked on a similar slope problem myself (although not for wind sim) in Lingo for our old Sentinel Islands game: flipcode.com/archives/07-17-2002.shtml

Also, just came across this timelapse video which has some parts which might be a good natural reference for you: vimeo.com/3744985

would make a great commercial for a car

very nice looking

It would be interesting if this could be exported to a directx desktop wallpaper.
