Navigation is very important part of user experience and Blurry makes it easier for small screens. It uses cutting-edge CSS3 techniques like blur effect for whole page (with fallbacks if blur is not supported) and various animations for menu.
Blurry is not a regular drop-down or vertical menu that you saw hundred times on WordPress websites. The plugin makes background blurry in sleek and amazing way. Your website starts to look like custom mobile application or game if you wish. For reference try to turn on Big Picture mode on Steam desktop app.
Plugin works on iOS, Android, Blackberry and Windows Mobile if device browser supports required features, if not it's just not generated.
