Fancy a game of Snake? Simply hit the down direction key on your keyboard when you see video buffering in an embedded YouTube video. Try it on the one above. Old? Who cares! It's Snake!
First, click play. When you see the ring of dots that come up to let you know the video is buffering, hit the down arrow and the ring will stretch out into a snake. Use the arrow keys to control your snake, moving it around the video to pick up dots to make it larger, just like the classic game. Hit any of the sides of the embedded video and you'll lose. I've found that holding your mouse cursor over the video and hitting arrow keys will restart the game if you lose.
If you're wondering what the above video is from, check sister site Japanator for the full story. The video comes from my impressions of McDonald's Japan's Miami Burger. Yes, those are tortilla chips.
