This is a random curling photo I ganked from someplace; I picked it because you can see the wall of the ice rink pretty well in it. This same design (or at least a very similar one) seems to be on all the ice rinks and painted on fences, etc, all over the place. If you've watched any ice skating, you've seen the one there. I just think it's really beautiful. Blue and green is not a color scheme that's been extremely popular in recent years, but it's one I always liked. Water and earth, I guess.
