This one's not for me..except after a few ales maybe..for those that enjoy winking at people but find it too bright to take off their sunnies on a bright day. To give a good wink..you could have a shutter eye(comes down on the outside of the lenses) operated by a little air bag held in the hand that when squeezed air goes through small tubing to the sunnies (same as those little jumping spiders you used to get, when you squeezed the bag it would jump) anyway the eye quickly winks giving the illusion desired, put this together with a cheeky smile may get you the response your looking for or have them knocked cleanly off your face.-- skinflaps, Sep 11 2002 Or have the mechanism attached to your eyelid so that activation occurs by way of an actual wink.-- globaltourniquet, Sep 11 2002 delightful Mr Flaps +1-- po, Sep 11 2002 Ah, skinflapping sunglasses. And maybe for funerals an option for shedding tears.-- FarmerJohn, Sep 11 2002 Make the lenses of the glasses from monochrome LCD screens. Mount a reflective IR diode/photodarlington pair in the corner of each eyepiece, aimed at the cornea. When the eyelid occludes the eye, the IR reflectance path is broken and the LCD shutter goes transparent. So you can be seen winking. Could run of a small lithium battery - the electronics could be integrated into the sidepieces. Cost about USD $500 apiece.-- 8th of 7, Sep 11 2002 If I wink each time the lens goes goes transparent, how do I ever know if it's working?-- FarmerJohn, Sep 11 2002 Ask a friend ..... if you have one .....-- 8th of 7, Sep 11 2002 Well, I winked at a friend, but then he walked away, quickly.-- FarmerJohn, Sep 11 2002 or perhaps ones which looked like a winky.-- dare99, Sep 11 2002 You would end up looking like Groucho Marx winking-- skinflaps, Sep 12 2002 random, halfbakery
