Goblin XNA Augmented Reality

Goblin XNA is a project at Columbia University that aims to create a platform for developing Augmented Reality (AR), or Virtual Reality, applications with Microsoft's new XNA game development platform.

this project is particularly interesting to me because I've just finished books on XNA (XNA Game Studio Creators Guide) and AR. Goblin XNA uses the ARTag marker system, which was developed by my AR co-author Dr. Mark Fiala.
