My submissions for your review. Design #33 is my favorite the concept is based on Stone Gardens creating form and function from sand and stone. This design is a river or stream flowing into a basin.
The orientation is critical in this design the opening facing upward so that the water does not over flow or spill out. The idea of pouring out or over flowing can be seen much later with horses over doors...the shoes are always tacked with opening pointing upwards a sign of good luck.
