It appeared on a dining room window yesterday morning... 
A frost patch that made me think of Yggdrasil, the World Tree of Old Norse mythology...
Yggdrasil, a huge ash tree, is a meeting place of the gods. It is the tree upon which Odin hung for nine days, pierced by a spear, to learn the wisdom of the nine worlds. Yggdrasil's branches reach far into the sky and its three roots spread wide to a spring and two wells. Creatures live within the great tree - among them a dragon, an eagle, and four stags. . .I think I see them . . .
