It's cool man.

I was so taken by the "Fretwork" on the window I had a shivery closer look.
I don't know whether it was last night's -7˚C or just the fact that triple glazing keeps the heat in even better than double.
Either way, I was quite intrigued and decided I'll have to work on something akin to this over the cool season; behold the 1st attempt..
