Kotaku has huge coverage of the Shigureden interactive museum in Kyoto, in which you roam all sorts of environments (based on a traditional Japanese card game) with a specially tricked-out Nintendo DS as your guide. Looks fascinating, although it does seem as if you’d need a minimum of Japanese ability to take everything in. There are a whole bunch of pics up, so just go to the Kotaku site and scroll down, but you can also try here, here, here, and here, with an intro to the museum here.
