I spoke below about roof tiles and thought that maybe I should explain why Roy is fasinated by them. It seems that the old families in Japan each had their own roof tile design so that is why there are so many different ones. Above in another design from Iwakuni families.
I am not sure this qualifies as an interesting picture, but there are few blogs that feature roof tiles so may be I can class the picture as unique if nothing else
This tile adorns a thatched roof.
