Google is well known for its love of gaming Easter Eggs, with Pac-Man and the ZX Spectrum referenced on its home page in recent years.
But today's search engine secret has to be its best yet; head over to Google.com and search for 'Zerg Rush' for a brilliant homage to Blizzard's StarCraft series. Amazing stuff.
Last month the search giant announced Google Play, the "new home of Android Apps" and games.
The service draws together Android Market, Google Music and Google eBookstore, with storage space for up to 20,000 songs and a selection of millions of media types to download.
