Does Facebook have a birthday present in store for us?

The site turns six years old today, and a couple of redesign shots have been seen in the wild. founder Sam Lessin tweeted these screenshots. In them, search has taken more of a prominent look, moving to the center from the right.

Most of the bottom navigation has been moved to the left-hand bar. Ads and applications get their special bookmarks on the left-hand, which the company has talked about since last fall.

What’s new in Lessin’s version is that chat has been moved to the left as well. Instead of appearing in the bottom-right hand corner in a pop-up, your online friends will stay continuously visible on the page.

It doesn’t seem to be consistent, though: another user, Laura Watkins, shared screenshots in which chat looks like it’s in its original position.
