Using the facial recognition API from face.com you can do the following, using only javascript:

• identify all faces within a photo
• detect whether a face is male or female
• whether the face is wearing glasses
• whether it is smiling

Each guess is accompanied with a probability score.

Check out this interactive widget which lets you submit any photo to the api (try your flickr account), and examine the returned data structure.
