Today's photo of the day is entitled "10 windows" and is by Tony Gravé. Tony is based out of Stavanger, Norway, although this particular shot was taken from inside a castle in the Italian city of Siena. Do make sure to stop by Tony's main photostream for a lot more great images.
Don't forget that I actually maintain a whole page of favorite photographs over at Flickr, for those who would like to see more. To express an interest in having your own work featured, just drop me a line at cclapcenter [at] gmail.com.
