Ice flowers

Isn't that what these are called (in Finnish I mean)? Ice fractals on the glass.

It was beautiful today, sunny and the white snow and ice glimmering. But it was also bitingly cold, -19 C in the morning and the wind adding to the chill. Better to take pictures from the warmth of indoors was my decision. I did go out a bit, had my camera too, but didn't really have the endurance to do much with it.
