"After a marathon two-and-a-half hour Google I/O keynote, the tech giant had one final surprise for attendees: a piece of cardboard.

Developers at I/O walked away with a strange construction kit for a project named, imaginatively, Cardboard. Cardboard is a way to create an Oculus Rift-like virtual reality viewer with your Android smartphone. Users can put together their Cardboard kits – which contains corrugated cardboard, some lenses, magnets, two strips of velcro and a rubber band."
