Nature’s pentagons, originally uploaded by jjn1.

I’ve always wanted to see the Giant’s Causeway in Co Antrim, and yesterday finally achieved that ambition. It’s a remarkable geological phenomenon, 40,000 interlocked basalt columns which were the product of an ancient volcanic eruption. We got there at the end of the day, as the sun was setting, and it was quite magical — and almost deserted, despite being one of UNESCO’s World Heritage Sites. I had expected only hexagons, but in this stretch the columns seemed to be mainly pentagonal in cross-section. And the light was wonderful. We ran into another photographer who was similarly transported by it.

I’d like to buy a Lytro light-field camera but, sadly, they won’t ship them outside of the US at the moment. Sigh.

On Friday night, after a lovely dinner in London, we stayed with some friends who have a flat in the Barbican in the City and on Saturday walked with them round the (half-frozen) lake in the centre of this astonishing development. On our way round, I suddenly saw this inversion.

Sigh. Remember film? Nor do I.
