This sucks! I can't vote, ok I can but I can't narrow it down to just 3. I'm going to but I want people to know that I loved so many of these. And it just isn't fair. Ok here are my final picks:
3 pts Nuski - King of the terrain editor. Works wonders with it. Using a 2D pic to create a shape in the terrain editor is legal in my book.
2 pts Catlin_mc - Wonderful concept and great modeling!
1 pt ICMgraphics - Another wonderful concept and I love those meta-cows.
I won't mention all the others I loved but I did want to mention that I wished I could have fit T-John into the top 3, it was a great idea and the terrain work was phenominal!
I think everyone did a fantastic job with this challenge.
