[Windcatcher]

I've been wondering about that same question for some time. I'm not all that confident that the live client would handle it unless you spawned the windmill as a "mob", sort of like the way ships are. I want to allow something like that for placeable objects, but it might only work in SimpleClient. Honestly, though, I'm not sure what would happen if we tried it with the live client (put an object in the xxxx_obj.s3d file that used skeletal animation), but it would be an interesting experiment. A side benefit would be able to place microvegetation on the ground where things like tall grass really do move with the breeze.
