Frost's Fine Etching

We are now in the first Arctic cold snap of the season. The daytime temperature barely made it out of the teens. And the recent rain and snow and the wild wintry winds (to 56 mph) began their usual etchings on our bathroom window.
Look at how the icy threads go every which way: horizontally, vertically, diagonally. If you look closely at the image below, you'll also see numerous "islands" of ice, spots which seem to have formed spontaneously. But even more importantly, look to the lower right where a loop of ice has formed. How is that possible? What could possibly bend the formation of ice crystals?

Or is the answer quite simple? Was it the wind?

This shot (above) is of the window on our porch (both windows presented face south) with the sun shining fully on the night's icy creation. Here the filigrees shoot off at odd angles and here, too, one bends.
Tonight we are to bottom out at 11 degrees and I suppose we will see new etchings made.
Because we fired up the kerosene heater for the first time this season - and because Dad is ill - I slept on the living room floor so I could keep an eye on things. But all was well, but for the dollars I hear the furnace burning.
