Wikipedia is following in the tradition of Google Labs by now allowing users to try out Beta Features for its site. All of the new features are opt-in and some are really cool.

Two of the most interesting new beta features are the revamped Media Viewer, which acts as a light box for thumbnail pictures on the site (a welcome improvement over clicking to a whole new page, which the rest of the internet left behind six years ago). Additionally, you can try out a new look for fonts with the Typography Update. Overall the changes aren't revolutionary, but if you'd like to take them for a spin, you can check out all the new beta features at the source link.
