Ever wonder what facial expression people make when they’re about to be hit by something via slingshot? No? Well, no need to keep guessing because the Sling Shot camera (designed by Sung Young Um & Jung Eun Yim) can help you to find out. Technically, sling shot takes pictures by vibration of elastic band. You can take surprised look pictures by stretching an elastic band. It can be folded when it is not used. The idea behind this concept camera is to free people from their inhibitions and let them relax in front of the camera instead of presenting the usual lock-jawed grimace. Flip out the y-shaped arms and pull on the cord and the lucky subject will recoil, then realize what’s going on, and then slump in relief with a genuine smile on their face. [link]
