How would you like to be able to control your phone and other household devices with a nod of your head? Turn up the volume? Turn on a light? Shut the garage door? Reply to a text? You can do that with The Elbee, a $149 wireless set of earbuds, that makes it easy to control your environment with head gestures or voice commands.
There are other devices out there that do something similar. The Moto Hint immediately comes to mind. I’m sure you could accomplish the same thing by using IFTTT (If Then Then That, now just called “IF”), but judging by the video on the Kickstarter page, you can do much more and the Elbee is stereo versus monaural. This might be something to watch.
