It seems everyone is getting into the April Fools spirit, including Google. On its front page, Google has a link to its new feature, Google Motion. The way it works is, instead of using the keyboard or mouse, you put your body in various wacky positions, and through your web cam, Google will translate your movements into words.
There's even a printable chart on the actions you'd do for common sayings like "Hello" or "If you're leaving for Buenos Aires next week..." Of course, this being April Fools Day, the whole thing is a farce. But check out the link, it has some hilarious deadpan videos about how Google Motion would work.
