We developed  an augmented reality game that enabled players to build their very own island. We produced a series of printed blocks each representing a different element and containing a unique code. When the block was placed onto a grid, our image recognition software recognised the element and added it to the island. Content messaging was delivered based on the player’s choices. By adding and removing different elements the player controlled the amount of  CO2 the island produced. The aim: to create a carbon neutral environment.
