Smart fan targets humans (in a good way)...

A step toward the robot apocalypse cleverly disguised as an improved comfort device, the human-sensing oscillating fan blows air only where there's a person to enjoy it. Seriously though, this is a textbook use of smart sensing: directing resources only toward the intended use instead of brute-forcing air all around the room, improving both effectiveness and efficiency. Just make sure yours doesn't become self-aware and use its targeting system for evil!
