Popcorn Indiana has manufactured a device for their Popinator project that shoots popcorn kernels into your mouth whenever you say the word "pop." Using binaural audio recognition technology, its popcorn cannon is able to swivel to the exact 360-degree direction the voice came from.
Aside from the typical voice fluctuation drawbacks you might face ("yeah, she's really popular- whoa! What the hell?"), it's a pretty darn neat little gadget. Think of it as Kinect for food!
