IMO this upgrade for Keimola by Jason is the finest one yet and it will permanently reside on my HD.  Here is a still most beautiful 3dfx friendly version of it,at least in my opinion as well.

AFAIK,this part of Finland has a a rather featureless landscape that is heavily forested. This is the sky/horizon I use.
