We’re about to start cramming all the filthy, raunchy thoughts we can get into our heads, because the vision of the future that the Muse Brainwave-Sensing Headband ($165) is showing us has us very afraid. This amazing device from Interaxon uses two sensors on the forehead and two behind the ears to measure your brainwaves and send that (likely perverted) information to a smartphone or tablet. You can then see if your mind is wandering, if it’s mellowed out, or if it’s in a state of deep focus. Sadly, we predict within a year or two,  the “man” will be able to tell just what it is we’re focused on. Stock up on smut, boys.
