I just released the first major version of my gem for the Flickr API called “flickrie”. The major difference from other gems of this kind is that it uses an object-oriented approach. Also, it’s written in Ruby/Rails fashion (for example, an attribute that is called #dateupdated in the Flickr API will here be called #updated_at, and #ispro is called #pro?), and you get all the information parsed (like dates, for example, you’ll get Time objects, instead of strings or integers). Check out the project page on GitHub :)
