Fans of 3D imagery can now bring that technology to their smartphones with the Kula Bebe device. The attachment consists of a lens that covers any smartphone camera's stock lens and a series of carefully angled mirrors. This layout causes the camera to take two photos at once, each from slightly different angles -- the same technique used in any 3D imaging.
Aside from the Kula Bebe itself, the company offers software to allow for several different types of 3D viewing. These include the old-fashioned red-blue glasses (i.e. anaglyph rendering,) a cardboard viewing headset that accepts phones (similar to Google Cardboard,) and an automatic "wigglegram" creator. A wigglegram is a GIF that quickly shifts between the two images in a 3D photograph, giving the vague impression of depth.
