Dark satanic mills?

Another iPhone shot, of THAT view (click label below for others), taken on my way home from work. I took the photo because I loved the sky and the reflected lights but in the finished image I like the graininess that the iPhone has rendered. It adds extra moodiness.

And did those feet in ancient time
Walk upon England's mountains green?
And was the holy lamb of God
On England's pleasant pastures seen?

And did the Countenance Divine
Shine forth upon our clouded hills?
And was Jerusalem builded here,
Among these dark satanic mills?

'Jerusalem' (words from a poem by William Blake, set to music by Sir Hubert Parry) has become a British anthem and one of the best loved of patriotic songs, played notably on the Last Night of the Proms.
