Google Chrome (included game)

When the Google Chrome web browser is invoked in an offline state and tries to load a remote website without having an Internet connection, it displays a small illustration of an 8-bit dinosaur. But in recent versions of the Canary testing version of the browser, the dinosaur is interactive -- pressing the space bar will drop it into a Game Boy-ish monochromatic desert landscape, where it runs, indefinitely, jumping over clusters of cacti with presses of the space bar. The game chimes celebration of every 100-point milestone and tracks high scores for the player to overcome in the future.
