- adj. Resembling a sink or some aspect of one.
Each tier looks like a sink and the liquid flows out what looks like the drain and then into the next sinklike vessel, where it cascades around the bowl in the other direction, and then out that drain.
Incidentally, the sinklike vessels were actually casts of a very pregnant womans belly.
