You haven’t decided the right Valentine’s Day present for your other half yet? Google Cardboard can be a great idea then! Cardboard is a fold-out cardboard smartphone mount that, when combined with lenses, a magnet, a piece of hook-and-loop fastener and a rubber band and held against the face, affords a virtual reality experience (VR). A smartphone with stereoscopic display software fits into this device and the lenses allow a person to perceive the images as one single three-dimensional image. The headset is designed by Google, and you can buy it here!
