Icy prison

The top room of our townhouse has these interesting icicles every winter. The sun was out and the sky was blue so it made of an interesting blip. They appear to be glass-like bars on the window keeping me trapped inside. But since it was quite cold today (-19C to start going to a high of -11C, and with a north breeze) I did not mind staying in. I can't wait for spring and my flowers to come back.
