 US Design Studio 'Something Like This Design' (Trygve Faste and Jessica Swanson) came up with this beautiful collection of ceramic objects that are both man- and sea-made.

The separate porcelain pieces were submerged in the ocean, allowing marine life like barnacles to attach to their surface.

Love this!
One little thing though: I do wonder how these objects smell.
Living near the seaside i brought home many a barnacle-clad beachfind, and though pretty, they don't exactly smell of roses.
