Sascha Pohflepp’s camera Buttons is different than any other camera, in that it has no lens:
It is a camera that will capture a moment at the press of a button. However, unlike a conventional analog or digital camera, this one doesn’t have any optical parts. It allows you to capture your moment but in doing so, it effectively separates it from the subject. Instead, as you will memorize the moment, the camera memorizes only the time and starts to continuously search on the net for other photos that have been taken in the very same moment.
