Step inside "The Unreal Garden." At the annual Los Angeles video game expo, E3, gamers are exploring a mysterious garden through the power of augmented reality. The 6,000-square-foot experience blends art, augmented reality, projections and soundscapes to create an out-of-this-world encounter. It's filled with glowing plants, interactive artworks, soaring octopuses and stingrays. When visitors create a piece of digital AR art, all the other headset wearers can see it too. The aim is to create a vibrant social experience in augmented reality.
