Yup, that's the famous Neuschwanstein Castle in the background. The guys at Walt Disney made it even more famous than it already was when they designed the castle of the Sleeping Beauty after it. The copy you can find in Disney Land in California. The original one stands in Schwangau, about two hours south of Munich.
Google Search by image
The other day I tried this new image search feature by Google. Have you heard about it? I noticed it after Scott Weyden tweeted about it. What it does is it lets you search for images, but not with words, but with actual pictures. You enter an image (or the address to an image) and Google checks for you on which websites this image is being shown. I tried it with "The Rat's View". And indeed, Google showed me a whole bunch of websites where people have used it. Here is one of those sites. I think this is pretty interesting for photographers or anybody who creates images. Give it a try!
