Since its creation in 1998, Google has become known for a range of things. These include not just the companys services, which have expanded from a simple search engine into the likes of Gmail, the Chrome browser and the Android operating system, but also the jokes and Easter eggs that the organisation inserts into its code. Many of these are blatant, including changes to the site logo to coincide with specific events and April fools hoaxes that have ranged from the announcements of new services (such as an Animal Translator) to humorous alterations of existing ones (such as 8-bit Google Maps). Other jokes and references, however, are more obscure, requiring specific inputs and actions to access. Some pay homage to a host of memes that have been popularised by assorted communities across the web, whilst others offer something more interactive than a mere reference. Without further delay, lets look at five such amusing Easter eggs hidden within Googles immense product portfolio.
