The Blending of the Real and Virtual: 19th century ironclad ships

I rather like the Russian wargame company TOTEM GAMES.  They run a lean operation from the looks of their website, but deliver on the gameplay.  TOTEM designs standalone, turn-based wargame simulations.  Specifically, on NAVAL subjects (a favorite) and even more specifically, on the 19th CENTURY (even more near and dear to my heart).   As part of their “gallery” on their one page website, they present pictures of nineteenth century naval vessels superimposed over a real photographic (water) background.  The effect is startling and very real looking.
