I'll second Ian's idea about shaping. Even though I'll not be in the contest portion, I don't think shaping (beyond tee's and bunkers) would be a great idea. It would tend to favor those who know sketchup the best rather than those who do the best job routing the course. Also, I don't think it will/should be judged too much on the artistic quality of the images, but on the quality of the routing given the topography.
For judging/presentation, I think it would be worthwhile for each entrant to give the sketchup file to the judges, but also to output an overhead with contour lines showing as well as a few of their favorite images with some descriptions. Then put the overhead and other images into a post on the actual armchair thread. Right now I forsee 2 threads. The "Contest" thread with rules, descriptions, some help info, some Q&A, and perhaps some preliminary images from either me, or the entrants for help purposes. And the "Results" thread with the final entries and perhaps links to the actual sketchup files, followed by judging results. Perhaps a third thread would make sense, with a listing of the winners (though you're all winners in my book) prominently placed, for eternal bragging rights (at least for one year anyway).
For prizes, let's get some suggestions going. One thing that's difficult is the fact that people probably live all over the place, but don't let that stop you from making some suggestions. I think it would be great if the winners got to meet/play a round with Yannick and/or the other judges (if we can line some more folks up) for some neat discussion of design etc. Unfortunately, I don't have any idea how feasible that is going to be. Let us know your thoughts everyone.
Thanks,
Charlie
