CCC: Plant Pot Shell

Spiralling shell and bokeh in large.

The Corpus gardener decorates many of the plant pots with interesting object that he finds around and about: there are shells, fossils, crab claws, curious fishing floats...! This shell is in one of the plant pots near my room.

I've uploaded some other garden macro photos to Flickr (right from this curious robin).
Highlights:
Honeybee in grasses
Snowdrops!
