Do you like Google Doodles, the whimsical commemorations of special people or events that periodically display on the search engine's front page? If so, we have good news for you. Google has just revamped the site where its Doodles are collected, adding filters for year and country. Doodles can also be found by tag or keyword, and some have behind-the-scenes descriptions of how and why they were created, like this interactive tribute to author Stanislaw Lem. Google has also added an online store, in case you always wanted to celebrate the Spanish Tomato Festival with a skateboard.
