For example I used the google translate drop-down bar so if you are from a different country, you can go to the drop-down bar to translate my whole page into your language so you can read what I'm saying, very useful for people all around the world that can't read english.
I also added this, pointless but fun, game called fish where you can click your mouse to feed the fish in the tank on the screen as the fish follows your cursor as if they are following their food. It's time consuming but if you have some down time and have no idea what to do then this is the game for you.
