Of course, I did a little looking around -- there wasn't much on the site at the time, and the only Web results that came up (like the Techcrunch article) referenced wiki search.
I was going to mention it, but I never got around to it.
Then, this morning, Boomtown, Techcrunch, and others of that ilk posted about it -- it's "visual search", which looks to be a Cover Flow interface over search results.
With the caveat of not having actually used it, I will say that visual search is like Snap Shots, or animated DVD menus: Seems like a cool idea, is neat for a minute or two, then gets annoying once you realize that it's not at all useful and actually gets in the way.
As to the purported "scooping" -- since I had no preview access, it's not like I had anything to report (unlike Boomtown and Techcrunch), and since I didn't attempt to do any actual investigating, it's not like I was trying to do any journalism (unlike Boomtown), but I still feel like I missed out on something.
