Frosty Patterns

It has been very cold the last week or so,but still there is beauty all around.

The frosty pictures are what I see on the side windows of my school bus. Yes it is cold,but isn't that pretty artwork.

I put in one picture of the sky. I just really liked how it looked yesterday before I started my bus.

I am making this post from an App on my phone,so I hope it looks ok.
The pictures were taken with the phone as well.
