I like the idea of being able to control where the nano draws water in from. right now, I get a bit of a circular flow across the top, down the other side, back across the bottom, and then up back towards the pump. If I can make it draw from the bottom even more, this would (in theory) create an exponential increase in circulation as a swirling vortex is created. Kinda like the little merry-go-round thing at the local park. You only put in a little extra effort on each push, but over time the constant additions of "energy" add up and you really get it moving.
