Pardon us while we freely admit that we have literally no idea what's going on inside a camera -- whether it's digital or those quaint film-based ones you hear about from your grandma. Luckily, our own kids might not have to suffer as we have: a group at the Computer Vision Laboratory at Columbia University have designed and built a prototype digital camera that should demystify the devices. The Big Shot digital camera kit, if / when it hits the market, will be a box of all the necessary parts for kids to be able to build their own simple, candy-colored digital camera. While the Big Shot is still in prototype testing phase, we really hope this gadget (and more like it) makes it to the market sometime soon.
