This year for our musical, we're doing Anything Goes. It's entirely set on a boat and we're building the front of the boat out in to our pit. The director would like some sort of effect that will put the "reflection" of the non-existent water in the face of the actors when they lean over the edge. The boat is about three or four feet tall so that is all the room I have to work with if I put it on the floor. Any ideas?
