Opera Labs is doing some extra-ordinary research in terms of new web-browser features and after introducing Opera Turbo they seem to have gone too far with experimenting introducing face gestures in the latest snapshot builds of Opera 10, the concept of controlling your web-browser with facial expressions sounds pretty cool but after seeing the video demo with man making funny faces to control the web-browser, I decided to stick with keyboard and mouse combination for a while, jokes apart the technology seems promising considering the evolution of touch devices where such functionality can be handy, I am very much sure that Opera will tweak this facial-gesture technology further to create something useful.
