You know Gmail and Google Maps, but have you seen the latest and greatest from Google's experimental labs section?
Google Books NGram Viewer
A spin-off of Google's Books initiative, the Books NGram Viewer lets you see how frequently people have used different words in print over time. Google also provides excerpts from the source publications showing the word or phrase in context. The graph illustrates how often people used the term 'Personal Computer' between the years 1950 and 2000. Another option is to track the fortunes of two or more unrelated words - say, 'snarky', 'fanboy', and 'gunsel' - head to head (to head), over the centuries.
Google Image Swirl
Google Image Swirl lets you look at Google Image results by relationship instead of just in a grid. This arrangement makes finding related pictures much easier when you don't use exactly the right search terms. Unfortunately, the demo works with a somewhat limited number of words and phrases so far.
