As we countdown the last few days of the year, please take a moment to consider how beautiful, rich and detailed the world is.

In a video game this fence might well be pristine, or maybe rust and moss would just be drawn on the surface but out in the world, each patch of green moss is fully 3D and, if only we looked, filled with tiny insect, and even tinier, microbial life.

On the other side of the park is a similar railing, but it has the remains of three or four layers of different colour paint, peeling and bubbling, and little moss, but much more lichen.

Every exposed surface in the city has some measure of similar complexity, and this is without even entering the park, or digging into the ground.

Life is wonderful, and we, you and me, being here to see it is a miracle, and as a total non-believer I use that word deliberately, if carefully.

May your 2026 be filled with childlike wonder.
