Don’t feel like shelling out the cash for a 3D camera? Instructables user “courtervideo” has put together a little device that harnesses the magical, mysterious power of something called a “mirror” to let you grab stereoscopic 3D images with your regular ol’ 2D camera. The method is pretty straight forward: two large mirrors places beside the camera reflect the image you’re trying to capture onto two smaller mirrors, which are then photographed. The result can then be viewed through a stereoscope, which will send one half of the picture to each eye, resulting in a 3D image.
