Leo has the newest Google product, which is made of cardboard. All of the attendees at Google I/O received a cardboard box that, once assembled, fits an Android smartphone. The box acts as a viewer for virtual reality, and the smartphone runs a cardboard app that will give each eye the appropriate image. Since the smartphone has an accelerometer in it, it will move with your head as you look around. This does the exact same thing as the Oculus Rift headset, which Facebook paid $2 Billion to acquire.
