Revolting Librarians: cult underground collection from 1972.

Fujifilm have developed a way of searching for people in pictures by highlighting a face and searching for it - all while the data is still stored on the camera ... no need to download and harness the power of the PC. The technology behind Face Search can look for other set patterns, but Fujifilm have selected the face as the most common thing that people will wish to index in their family photos.

Truly cool indexing that can fit in a back pocket.
