I am working on several NTrak modules and I would like to have an animated waterfall. I know you have all seen the lighted pictures of Niagra Falls in shopping malls, the one where it looks like the water is flowing in the picture. Is something like that possible on a module? Tried several revolving drum ideas with a light inside it but it did not give the illusion of flowing water. Anyone have any ideas. Here is the area that I want to place it.
