UFO in Oxford Circus

I saw this and thought "Schrodinger's cat would like to play with that"
It looks like a prediction of the position of the electrons on a big atom.
I am sorry if that is all a bit strange - just the way my mind works sometimes.
Anyway, in the big smoke again today, absolutely fabulous scene from the train travelling through the fields between Tottenham and Clapton - the frost covered ground, a layer of thick white mist about 10 feet high with a white base and pink top, brilliant blue sky above. Sorry no Blip, I was jammed up against all the commuters and no way was I going to be able to get the camera out of the bag between my knees.
Anyway usual stuff in London, Central line signal failure, Circle line broken down train, District line staff shortages. Finally coming above ground at Oxford Circus after circuitous route from Liverpool St and I saw this - just the one.
Journey back was less crowded and still a lovely day.
