This post is partly in thanks to Roma for including me on her favorites list. One image that I know she liked, "ice art 2", is one of the most ornate displays of window frost I've ever seen. It grew like a plant from the bottom of my window, with many branching stems.

Some time later, I posted another shot of the same piece of window from a different day, titled "son of ice art 2". The growth in that case seemed to follow a very similar overall pattern, but the stalks looked fairly different. These two images are shown together in a workshop.

The current post, "grandson of ice art 2", grew on the exact same expanse of glass months later, and is somewhat of a combination of the previous two. It shows stem structure and branching similar to "ice art 2", but grew mostly from a different spot along the bottom of the window.

The similarity of these three images makes me think of some historic snowflake pictures I saw recently. When the conditions for crystal growth were carefully controlled, the results looked similar. Significantly different growth conditions gave a quite different appearance.

The same thing is obviously happening here, but I don't have a clue what the most important factors are in crystal growth. One possibility is the debris (dirt!) on the window, which provides nucleation points for growth. On another window which had consistent but much simpler patterns, I wiped the surface clean one day and have not seen anything similar since. After that experience, this window will stay dirty!

amazing artistic capture, TFS Ori

Wonderful ice etching... another beautiful design from the Creator Himself and nicely captured by you. Well done! TFS Bob.

Hello Bob,
What an amazing artistic display you've captured. Very good exposure and lighting with excellent detail!! TFS.
You just gave me a really good excuse to use on Rosie whenever she gets on me about my trucks windows being dirty! I'll tell her to take a look at the beautiful image it will eventually create!!!
Thanks again!! From me and all the other husbands in the world!!!

Hello Bob!
This picture is really great artistic photo! We often overlook the beauty of the "frozen world" :> Great capture and documentary picture.
All the best from Poland,
Radomir

hello Bob!
really incredible graphic art of ice on the glass windows....

Hello Bob,
Beautiful and fascinating photo of this frozen window.
Very special.
Regards,
Peter

Hi Bob,
An amazing shot of these ice crystals!
The first thing that springs to mind is fractals.Of course,the mathematical formulae that express fractal geometry are relatively recent discoveries (thank you Mr Mandelbrot),but fractals have always existed in nature,and it is in this kind of image,and in the unfurling fronds of ferns that we can most readily see how they shape our world.
Interesting theory about the dust on the windows.
It sounds as though the reason for the growth patterns in these crystals is as much a mystery as the growth of helectites in caves.
It could also have to do with the prevalent localised air currents across the window.
Very interesting.
Cheers
Steve
