You may need to click on this photo to see why I took it yesterday.  I was on a flight back from Russia but I'm sure that anyone who has flown anywhere above a certain altitude and has had a window seat will have noticed the crystals of ice forming around the specks of dust inside their window.  Perhaps I was slightly oxygen deprived, but to me they looked like constellations of stars and I was reminded of the Dr Seuss story of How The Grinch Stole Christmas, or more accurately the opening and closing sequences of the Ron Howard film of the book.  It's the only film I can think of that references the hidden patterns of nature (with an existential twist), which is one of the many reasons I'm looking forward to seeing it again, and again.
