The Search Stories Video Creator is one of the coolest YouTube tools ever. Enter up to six queries and choose a musical track, and the video creator will produce an animated spot a la Parisian Love, that Google ad that told the story of blossoming love through search. When the video's done, you can upload it to your YouTube account.
With this tool you get a professional quality video - good enough for the Super Bowl, even - for free. Imagine all of the ways this could be used - business ads, nonprofit campaigns, photo tours, math lessons, travelogues, comedy videos... Each one would be an ad for Google, but worth it for the creativity that can be unleashed.
