Inkblot Auth is a class that can authenticate users by showing them inkblot images. It can associate a given user password with a list of inkblot images. The user chooses the password after seeing a list of inkblots and types in what those inkblots look like. The class can authenticate the user after showing him the same inkblots in a random order and asking the user to type in what those inkblots look like.
Instagram API integration with PHP can access an Instagram user's account using its API. It can send HTTP requests to the Instagram API Web servers using the OAuth protocol to access the account of a user with his permission. The class retrieves a token which it can use to send subsequent API requests to get the user feed, the user publications, the followers and who the user follows, and the user's most popular photos.
