Tidewalker

One beach, shared

Tidewalker is a slow walk along a shore that never ends. Look down, notice something, pick it up, turn it over in your hand. Keep it, or put it back where it lay.

Everyone walks the same beach. Each shell, stone, piece of sea glass and driftwood is made once and exists once: if someone keeps it, it's gone for everyone. The tide brings new things in twice a day, following the real moon.

Finds are meant to be hard to come by. That's the point.
