This is a conceptual sketch of Salmon Falls, a mosaic water feature I’d like to build someday. Water sheets down into a recessed pool at the bottom, allowing people to approach and touch the stone. The stone will be a mixture of textures, rough quarried surfaces as well as honed and highly polished finishes. I imagine the salmon themselves to be sculpted in such a way that they are raised from the flat plane of the wall.
Really, this would work just as well as a dry mosaic, without the added element of water, which would reduce installation costs, maintenance costs and allow more interaction.
A couple of years ago I made a similar koi mosaic that lays flat as a patio.
