Time was when software developers hid features in software that would only be revealed if you knew a convoluted sequence of key strokes. Often these so-called Easter eggs, were just lists of the programmers who had written the code, but they were sometimes much more. Software publishers eventually decided that this wasn’t professional behaviour so they were banned and pretty much died out. However, if you know where to look – especially in Google products – you’ll still find hidden treasures today.

The image below, for example is from GTA:San Andreas. You can use the jetpack cheat to fly up to the top of the Golden Gate bridge and you'll see the message. More of an anti-easter egg, so let's get on with the fun stuff.

8. Mozilla Firefox provides information on certain technical topics using the “about” instruction as you’ll see if you type “about:plugins” into its address bar.
