Sorry for it being a bit fuzzy, I am too lazy to re-size it properly.
But anyway.
This is how it works.
You put water in the top left shelves and it begins to duplicate as it falls down the pyramids.
the water will eventually collect in the storage tank.
Then you put the lava in the bottom right shelf where it also duplicates. Falling to the top layer of the water.
Now the lava doesn't change the water level because there is a source of water above it, keeping it on the same spot, so you can mine obsidian from one spot.
Another note.
Somehow i got the idea that corrupting it would be fun..
