A lfs in Nashville has one set up as one of their frag/coral tanks as an infinity look where the water is flowing over all the sides of the glass as to give the image of an endless amount of water in the tank and it is very very cool. They dont have any fish in it though and the snails actually crawl out of the display and are on the edges of the top and all around the bottom where it feeds back into the sump. There is a boundry around the bottom that is about 4 isnches wide and 5 inches tall at the base of the tank where the bottom boundry has a unnoticable slope just enough to get the water to flow to the two returns that are on opposite ends of each other.
Dont know if you can imagine this or not from what I have stated but that is the way i would go if I were to set one up.
