Maybe I dream a bit too big but I have this vision of a multi story tank that is triangular and follows the stairs up so that there is a depth range of 10feet to less than an inch. I used to work at the museum and I talked about it with some people there as an idea when we were designing the aquariums. It would be really cool to show off a shoreline habitat of the ocean or a cross section of a river. If i ever open a zoo or Museum of my own, it will have this.
