The other day day I visited the Belvedere Palace. In the back garden there was a fountain that was made to look like a geyser shooting out of volcanic rock. This was so lovely. Why don't I see this more?
I kept walking and stumbled on the Hochstrahlbrunnen Fountain. They were going for a similar effect, but it didn't work. The center part was clearly a ring of stones, and the small outer jets stuck out of their stone clusters too far.
So after seeing something I loved, I was immediately shown how it could go wrong.
