Hidden cameras: one place you'd like to put one and one place you'd never want to find one

i would like to put a hidden camera on my glasses. i guess it would be more or less built into the lenses. it would be a still camera that could sense where my eye is focusing so the photograph it takes is EXACTLY what I see and how i see it. i know that a regular camera does pretty much the same thing, but it always sets you back a few feet. plus if it was hidden you could get some pretty amazing candid shots. oh and to take the picture all you'd have to do is just blink a little longer than normal. as you can tell i have thought about that before!

i certainly would not want a hidden camera in the bathroom. that's just gross.
