Involuntary blinking devices — the new 3-D glasses? In an effort to do away with those pesky 3-D glasses donned by many moviegoers, a Brazilian production company called Jonathan Post created a blink-inducing device worn on the head that makes you look like a lunatic person. And oh yeah, the device, 3D No Glasses, allows users to experience three-dimensional visions sans disposable glasses thanks to all that crazy-looking blinking. And a second oh yeah: The much-viewed video of 3D No Glasses being demoed by a hirsute Frenchman named Francois is one elaborate, well-executed joke.
