Google is continuing to demonstrate what's possible with a modern web browser like Chrome. Among these possibilities we have a doozy: World Wide Maze lets you turn your favorite website into a 3D marble-based puzzle.
To experiment World Wide Maze you'll need the latest desktop version of Chrome, or a phone running iOS 5 or
Android 4.0 or greater. 
Synchronize your desktop and mobile browsers by entering a code, or using the Chrome Tab Sync feature. Finally use a keyword search to find a site to turn into a maze.
