Anyone know why there always seems to be different pattern of ice on glass?

Mr Google

Window Frost
Window frost forms when a pane of glass is exposed to below-freezing temperatures on the outside and moist air on the inside. Water vapor from the air condenses as frost on the inside surface of the window. The picture at right shows a patch of window frost about the size of an outstretched hand. Window frost often makes elaborate patterns as the crystal growth is strongly influenced by the window surface. Scratches, residual soap streaks, etc., can all change the way the crystals nucleate and grow.
Window frost was more common in the past, when houses still had single-pane windows. The newer double-pane windows are much better insulators and thus not so cold on the inside surfaces.

Very interesting, Lolly.

I have photos like that which I took in Canada many years ago. We had double glazing and central heating, however with the terrific cold weather, we still got frost 'flowers' on the inside but never felt the cold as we did in Ellesmere Road in the mid sixties with no central heating.............Brrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.
