When I was starting to design my book cover, I wanted to do something cool. I am using QR codes throughout the book to provide quick access to more detailed information. I thought that there must be some AWESOME things that can be done with QR Codes so I started to poke around.
I found a website that is providing Augmented Reality QR Codes, or AR Codes. They provide a few options, but also you can code your own.
With their AR code you can create a fully immersive experience, shortcuts, and fly-over experiences. The code can be printed onto any product imaginable.
They partnered with me on the creation of this code for my cover. I hope that you will find some really cool applications for your own use!
