This is an image i rendered today:
http://artificial3d.tripod.com/images/place.jpg [beware of tripod]
No image textures were used for the background, i used the regular blender cloud texture and other techniques to generate “realistic” moving and flowing clouds.
You can see this image and other new ones at my site: http://www.artificial3d.cjb.net/
The EC- project is also there.
