Starting in 1979, programmers and creators have found neat little ways of sneaking extras into everything from video games to software to movies. Most of us never even realize they are there, but to those creative enough to seek them out, there can be many rewards.
If you're a movie buff like I am, you may want to check out DVD Easter Eggs and glance through to see if there are any interesting things you've been missing out on your movies and television series'. Ironically enough, in Season 3 of Doctor Who, an episode titled "Blink" deals with these virtual Easter eggs hidden in DVDs as part of the plot.
Then there are more interesting ones. Especially in video games. Say, for example, the new Rockstar Games 'Bully'. A few choice moves and you can do something other than beat up on people. You can get a few of the boys to make out!
Don't believe me? Well, someone did a nice job of recording a screen capture from their makeout moment...
