Taken with the challenge in mind at Çinili Kösk. I was so intrigued by the light on the floor that I didn't realize I was holding up a group of people who wanted to get into the room. I was having problems with the focus on my camera while there (something got mis-set and I couldn't figure out what) so had a terrible time getting pictures, but here are the windows that were casting light on the floor: http://www.pbase.com/image/55990145
