edstromp points out this New York Times "story on using a pocket pc to translate a street sign. It requires at least a dialup connection as it sends the photo to a server for the majority of the processing: OCR, translation, English overlay for new image, and then transmission back to the user. All said and done, it takes about 15 seconds to translate a street sign. Put this with some augumented reality, and you have a rather useful tool."
"An idealist is one who, on noticing that a rose smells better than a
cabbage, concludes that it will also make better soup." - H.L. Mencken
