At Shine, a bar in San Francisco, they recently installed a Photo Booth that automatically uploads pictures to Flickr.

The clever concept seems to be a big hit and it illustrates quite well Flickr's potential and growing success as a social network application.

Even Flickr's founder - Stewart Butterfield and his wife Caterina - appear in the Photo Booth gallery, looking sweet and happy!
