You know, I'd thought about things in the spheres themselves but hadn't thought of that being part of the replenishing. I like that! :o) I'm also going to give a shot at making some whitewater around the splashes. I agree that that might give it a bit less static appearance. For the height thing, I think I'm going to try altering the view just a little so that one of the spheres is right in the front where only a part of it is in view. I'm hoping that'll give a better frame of reference of size and distance. Lordy, you all are great! :o) Susan
