Etsy have a cool Polaroid camera on sale which has been converted in to a working webcam for a PC. The conversion was quite difficult as the camera had to be hacked apart and cut open so the creator could reach the area behind the lens.
The finished product still looks just like an old Polaroid camera, but has a 1.3 megapixel Rocketfish webcam built in. The camera is compatible with Windows Vista, XP and Mac’s. It is currently on sale for $50.
