I am still mad at Google for killing this project. Picasa was the best photo app EVER! It was also very commonly used among genealogists and in genealogy centers where visitors often have low computer literacy. The facial recognition was fantastic! As far as I know, it all ran locally. It was great to be able to just select a person and go through all of the photos with that person in them. Great for genalogy, too. I wish they would open the source code on this!
