There is no end to experimentation, at least not after looking at this crazy innovation. See what you get out of this wild masterpiece. Pressing a button is no more a criteria to click pictures. According to Andrew Schneider, he simply needs a Polaroid camera with a momentary push-button switch instead of a mechanical switch (usually found on the older models) to trigger the shutter.

Andrew Schneider came up with an idea to make a wearable camera that takes the picture of the wearer simply by gestural actions and evades the need to press any button.
How to go about it
First you need a Polaroid camera (an expensive practice though). Then comes the time to lacerate the camera and make few adjustments with respect to wire placement etc. Here comes the time to translate the movement of eyelids to the opening and closing of a switch. Using conductive fabric, conductive thread and some spirit gum.
Cut the conductive fabric in thin strips and fray the edges to give them more of a fake eyelash look. Carefully sew the conductive thread to the lashes at one end and to the other half of the snap connectors at the other. Keep one thing in mind that the leads don't touch each other.
With the switches wired up correctly, the wearer has to close both eyes at the same time to get the shutter to release. This way all you get are pictures with the wearers eyes closed.

Personally speaking this is an effort worth appreciating but this expensive practice, and face mapping is not that most of us would want to practice at least not at the cost of experimenting with our faces. What's the point clicking such pictures when you yourself would take a while recognizing yourself (don't believe me? Have a look at the picture, poor soul!)
