Google Cardboard

Google Cardboard, announced in Google I/O on June 25, 2014, is a cardboard cut-out smartphone mount. With a smartphone inserted, Google Cardboard allows the user to have a Virtual Reality experience by holding it close to his or her face. While Google Cardboard requires a smartphone with stereoscopic display software, this simple and affordable device is constructed with lenses, a magnet, a piece of hook-and-loop fastener and a rubber band.

With no official manufacturer, Google has listed the schematics and instructions for the device on its website.
