Here is one by  Jake Spurlock called PetoMundo. And you guessed it, its a site about pets.

The first release of BuddyPress is due before year end.

It’s been a few months since Automattic announced that they will release a set of plugins (BuddyPress) that will transform Wordpress MU into an open source social networking engine.

Completion of the first public iteration of the plugins is set for the end of the year.

Now the first mock-ups of the Wordpress MU Buddypress enabled Home page have appeared. And it looks promising.

Wordpress’s look, feel and functionality is almost fully customisable, but this mock-up is a good visual guide of the power these new plug-ins will introduce to Wordpress. Note the sitewide activity feed. Ideal for smaller social networks (Each individual member also can have an activity feed, similar to Facebook’s newsfeed).

You can join in the discussion about the Buddypress mock-up.
