Sandbox AR Lets Users Create Virtual Worlds or Augment Their Own — All Linked to Real World Knowledge

Excerpt:

Once a user has their Sandbox AR scene built to their satisfaction, they can take photos or record a video walkthrough with their own voiceover, to introduce their classmates or their teacher to what they created or what they learned, for example.

To help educators leverage the power of AR wherever learning takes place, Discovery Education has made the Sandbox AR iPad app available for free in the Apple App Store.
