We have covered quite a few art projects using augmented reality as their canvas, but nothing of the scale of Biggâr. Created by Sander Veenhof, can best be described as a virtual sculpture composed of more than 7 billion blocks encompassing the whole world.
Using Layar, you can not only view Biggâr but also interact with its blocks. A single tap on your phone is all it takes to change the color of all 7 billion blocks (sadly only three colors are available to choose from). I failed to experience a live color change, but it should be quite a trip.
