Anyone has an original idea for a fountain ?

Tweet

So I have made a huge pond in my backyard, and I like the idea of sitting this summer at the border of the water, just looking at my fish and waterflowers. Now my wife has got a good idea : why not build a water fountain in the center of the pond. Since I don't like the plain waterbeam going up, and as the pond is big enough I am asking you for original fountain-ideas... Metal, wooden or stone constructions, high or broad : I welcome your ideas ! Put a picture with your response if possible, and maybe someday I will construct your thoughts...
