Here’s a game that you can play in your browser that shows off what’s possible with HTML5 and what happens when you run HTML5 in Internet Explorer (hint: it runs much faster!). It’s the World’s Biggest Pac-Man game!
The World’s Biggest Pac-Man game starts with the standard Pac-Man board, but if you go into the tunnels on the sides of the maze, rather than emerging from the other side, you emerge in a new Pac-Man maze. And there are a lot of them. Hence the name.
The World’s Biggest Pac-Man runs on any browser that supports HTML5, but thanks to the hardware acceleration, it’s even nicer on Internet Explorer 9.
