"Creative packaging is one way to entice consumers to purchase more and it might not get anymore creative than virtual reality viewers. Coca-Cola helped to create three different ways in which people can turn its cardboard materials into something useful afterwards. Using everything from the art of origami to an insert, these virtual reality viewers are easy to make and fun to use. More than that, they give the cardboard a second lease on life. Instead of being chucked away into a landfill, they can be used as an affordable alternative to more expensive virtual reality viewers. All a person needs is a smartphone and some virtual reality apps to make the viewers come to life. Everything after that is pretty easy and intuitive to use -- at least for tech-savvy people."^^<http://www.w3.org/2001/XMLSchema#string>
