Impossible to catch the full glory on camera. Louring cloud blots out the shimmer, until the next sunburst. Angle and alignment is everything for refracted light: the sun, the raindrop birch, the raindrop glass of the window, and me. Outdoors and looking up into the trees the effect is lost. It's about coincidence.
Listening to Thought For the Day this morning, I was taken back to Liverpool and a Sunday morning exploring in the vicinity of the University Sports Centre.
