The only reason I can think of, to post this Idea, is to warn folks about what to look for, should someone actually implement it sometime.
A pair of shoes is modified to be all glittery. The glitter disguises the existence of an upward-facing (and reflective) camera lens built into the top part of the shoe. Cameras are so small these days that an entire unit could be built into a shoe without discomforting the feet. Wires could run from the camera unit to the inside of a pants-leg, where batteries and image-storing hardware can be located separately from the camera.
Dress-wearing or skirt-wearing ladies should be particularly on the lookout for such shoes!-- Vernon, Sep 07 2015 Like this? http://assets.nydai...pskirt24n-2-web.jpgNot glittery, but real, especially for up-skirt pervs. [neutrinos_shadow, Sep 07 2015] Glittery shoes http://www.celebitc...09/wenn21732777.jpg$2 million in diamonds, but no camera [Vernon, Sep 09 2015] This was productized 6 years ago http://gizmodo.com/...ly-get-you-arrested [MaxwellBuchanan, Sep 09 2015] I hate to tell you this, [vernon], but you missed that particular wave by about 10 years.-- MaxwellBuchanan, Sep 07 2015 Oh my. Thank you for thinking of us gals. I shall now insist all men with glittery shoes that approach me, take off their shoes. Just in case. That should happen about...Hmmmm...ONCE IN NEVER. But I like the idea anyway, of an upward facing camera, the perspective would be awesome, for looking at the clouds. Yay. +-- blissmiss, Sep 07 2015 He's missed the patent leather shoe wave by at least 60 years.-- tatterdemalion, Sep 07 2015 //Dress-wearing ladies should be particularly on the lookout for such shoes!//I say, you forgot to close your Terry- Thomas tags, Vernon, old chap. Here, let me help you </Terry-Thomas>. Phew!-- calum, Sep 07 2015 [MaxwellBuchanan], most cameras available to Joe Public were not that small, ten years ago. See [Ian Tindale]'s link for evidence of that. Today, the easy availability of quite- small camera units (see your average smartphone and even average portable dumbphone) is what makes this Idea worthy of being concerned-about.-- Vernon, Sep 08 2015 Outfit all thirty students on a 15 countries in 8 days tour with shoes like this. They would snap thousands of random photos. Then take the photos, add a narrator, and make an underground travel movie.
Things would mostly be looking up.-- popbottle, Sep 08 2015 [Vernon], see link for the same thing 6 years ago. Small digital camera modules were certainly available a decade ago from electronics suppliers such as RS or Farnell, having been in mobile phones since about 2000. My point was that this idea is fairly wkte.-- MaxwellBuchanan, Sep 09 2015 [MaxwellBuchanan], OK, point taken --except for one teensy thing. This Idea mentions glittery shoes specifically to disguise the existence of the reflective camera lens. Any ordinary shoe with just a single highly reflective spot will attract curiosity as to what is causing the reflectivity. For generically glittery shoes the answer could be so obvious that one would have to be specifically suspicious of a possible camera --as indicated by a warning in the main text!-- Vernon, Sep 11 2015 Oh cute, now I can virtually walk in the paws of two little mice.-- wjt, Sep 13 2015 I wonder if ladies will ever wear chunky platform heels with a battery hidden in the platform and camera in the chunky heel and take videos of strange men following them around?-- travbm, Oct 29 2015 random, halfbakery
