The Flickr Walkabout is a way to randomly wander around the Flickr photo community. Enter a word in the box above, and click a button to build a slideshow. If you choose "this word," you'll see images tagged with the word you've entered. If you choose "related words," you'll see images tagged with words that Flickr considers related to what you've entered.
For each slideshow, you'll see a list of related tags to the right of the images. Click on those to wander further into the Flickr community.
