I thought a wave machine was a perfect gift for a back garden.

Maybe. Lava seems pretty slow, though...
What I built wasn't complicated. There's another version to the... er.. west? of their cane harvester :)
I've not seen it yet (will check it out tonight) but does your machine push water beyond it's flowing limit on flat ground?
I'm planning a moat and would like to fill it with water.
