The other rotation I attended was for Layar, which is very similar to a QR code. It is different in that you are able to turn images into links, like I did here to the left. Download the Layar App on you iPhone or iPad and scan the photo. It will link you to the website I added, which is Alta.com. This would be awesome to use in the classroom and to share more information with your students.
