If you've been following YouTube Geek Week, you may have noticed that YouTube has been releasing one Easter egg per day this week.
For instance, one command lets you defend the video you are watching by playing Missile Command, the 1980s Atari game, in your browser. If you're as bad as the Big Think editor who attempted to defend the Lee Smolin video below, it will look like the image above. Type "1980" on any white space on the video page and you can play. The game is compatible with Chrome, Safari and Firefox browsers.
Here a few you can try on the video below.
-Type “1337” on a video watch page and check out the comments
-Click “Pow” button on the player bar
