Have you ever been too lazy to type in your Google search query? If so, consider Google MentalPlex search. This Google service figures out what you're looking for before you touch the keyboard, by analyzing the previous five sites you visited and factoring in your local air pressure, your astrological sign, and the "speed and vector of your mouse movements." Okay, you didn't have to conduct an imaginary search to figure this one out: Google MentalPlex was the April Fool's Day hoax for 2000.
