The Blind Camera is perfect for those people bored by the mass-produced point and shoot cameras. There's no viewfinder, no lens, or flash. All it has on the outside is an LCD screen and a shutter button.
This art project by Sascha Pohflepp combines a Sony Ericsson k750i with a black case to let you take other people's pictures. The design works by recording what time you click the button to "take" a picture, then later on connects to the internet to scope out shots other people took with that same timestamp.
