In my portfolios you'll see that I install a lot of hand-made (like the dragonfly and leaves above) and hand-painted (like the sea otter below) tile.

All of these beautiful pieces were created by Arrow Clayworks.  The artists there would love to make tile for your project as well.  Click on the sea otter below to see samples and get ideas.  They can re-create anything you see or design something new based on your specifications.
