We have a wave generator at my old university, nothing to that scale, but it it had an array of paddles on one edge of a cube, and you could generate different shapes of wave. Like a CNC wave generator. You could even generate a swirling vortex. It was a pretty cool thing. We tested robots and offshore energy harvestors.
