Google is in a mood, and when it's in a mood the company starts hiding features that surprise its users. New version of Chrome Canary, contains a hidden game, which you can play when you are not connected to the internet.
It features the familiar T-Rex dinosaur but not in the static pose we all know. The game as mentioned above is only accessible when the program browsing it detects you're offline, and it's completely hidden unless you know where to look.
So if you have the new version of Chrome Canary, go offline (don't worry it won't hurt) open the browser and wait for the dinosaur to appear. Tap it key of space, and the cute T-Rex will jump. The landscape around him will grow to the right, and he will be able to jump to avoid obstacles.
