Frosty windows

Our window cleaner gave us some money off yesterday as he was unable to clean the windows of the back porch because they were frozen solid! There is no heating in there. This morning they had defrosted a little bit creating some lovely patterns on the glass. 
My blip is a collage of the original photo at the top, showing the three panes of frosty glass, with two more of the same photo altered with filters. It gave me something for a little while to do on a cold winter’s afternoon indoors!
Thank you to Ingeborg for the AT challenge although mine does not fit the optional theme.
