IMPLEMENTATION 275. Hide Some Easter Eggs Have fun with the solution and include an “easter egg” (aka undocumented, hidden features) in the final product. 1 Some classic easter eggs include: • On the Original iPod: Select About from the main menu and then hold the center button for a few seconds to launch a mini version of the game Breakout. • In Mac OS X: Type cat /usr/share/calendar/calendar.lotr into a Terminal window to display important dates from Lord of the Rings. • In Skype: Type [drunk] or [ninja] to see some hidden emoticons. • In Google Earth: Hit Ctrl+Alt+A (Cmd+Alt+A on Mac) to launch a flight simulator. • In Mozilla Firefox: Type about:mozilla into the address bar and you’ll see a quote from the Book of Mozilla. 1 The term easter egg for this type of hidden feature was coined by Atari after the programmer of the game Adventure left a secret message in the game. The message? “Created by Warren Robinett.” 143
