The latest version of everything (including the doorbell and letterbox) is on my new server at http://imaginatorium.org/, but for the time being I'll leave the old copy here, so as not to break existing links. ("You know what to do with your bookmarks.")
Well, unfortunately this no longer makes sense. This is the old design for the Imaginatorium front page, which I've replaced by a column of photographs. So the letterbox and hyousatsu, the Japanese-style name plate, have been thrown back here to collect dust.
