I note this as a curiosity, I've been scanning my comic book collection into iPhoto for a while now and when my computer died last weekend I got a new mac mini with a new iPhoto program. I was looking at Howard the Duck 24 and when I zoomed into the first page I got small boxes with 'unnamed' in them. It took me a bit to figure this out, in the new iPhoto you can select regions of the image scanned in and label it as a face and those faces are cross referenced not only with other such faces in iPhoto but I think in your contacts as well. The program looked at Gene Colon's art and managed to recognize faces. I'm going to look through and see how many other things the program recognizes as faces.
