I hope NASA produce another photo of GB after the snow has melted. It'd look a little like those fragments of decomposing sponge washed up on the beach from time to time.
Last such fragment I found was on Tynemouth Long Sands: an all-but-complete seat cushion kept afloat in the wellspring by Crusoe's Cafe by the water bubbling underneath it. I fished it out, feeling the rubber-watery weight of it around my hand before dropping it like whale blubber onto the shore.
As I left, I was aware of a kid behind me, fascinated, picking it up and dropping it back into the spa.
The sea is ripe for symbols, and the sealine the place they venture into consciousness. I still remember, passing the Rendezvous Cafe two or three years ago, seeing a complete copy of the Quran furled/ unfurled in the waves, whether coming in or washing away I couldn't tell.
