Those guys at Google are putting some interesting things out at the moment. Real time searching was released on Monday and finds real time updates from news feeds, blogs and twitter, displayed as part of your regular results page. If you leave the search page open, it continuously updates. Used it a couple of times and it's rather good.
Then they announced Google Goggles - a new way of searching using pictures. Currently only available on phones running Google's Android OS but soon to be released on other platforms (hopefully iPhone next....), you can take a picture on your phone and Google will return search information back to you about whatever it is you've snapped. Released at the moment in beta, it currently supports photo-based searching for books, DVDs, landmarks, logos, contact info, artwork, businesses, products, barcodes, and plain text. You can use it to take a picture of a label on a bottle of wine and get info back about the vineyard, or take a picture of a piece of art and find out what it is. I can't wait to try it - first reports are that it's impressive. There's Google's own video below, or you can go to YouTube where there's lots of examples of it being tested with some very good results and some not so good, mainly on those things that Google have admitted they're still working on.
