*Tiny electromechanical MEMS hardware stuck to the surface of my eyeballs …
but the man's right, that IS feasible. It doesn't violate any laws of physics (except that you have to *beam some wireless power into them* — ouch…)
*So much for that cornball geeky plastic "heads-up display* problem. In fact, why not dig that useless Shakespearian jelly out of your eyes and fill the whole socket with gelatinous MEMS?
