i grabbed some polarized sunglasses recently and they're really cool but they just make me want to make an eyepiece with a polarizing lens that I can rotate freely without having to put my head at weird angles
the cool thing about this is that it takes an element of the world that's normally difficult to directly experience and makes it available as a visceral sensation. I often fantasize about having stuff like auditory, infrared, ultraviolet cameras for the same reason. You take something that seems abstract unreal and you make it into a part of your worldly experience
