Product and sales training in a 3D environment

I've been making notes and currently exploring learning opportunities in SL, but haven't grouped my thoughts together enough to make a decent post yet.

In the meantime, I'd like to share this informative video about using 3D worlds to enhance learning. The video shows an example where sales reps are trained about the features of a new product. The creator of the video, Karl Kapp, has shown a 2D learning approach in a 3D world, and how it can be made more effective by taking advantage of the unique features offered in a 3D environment. Clearly, the 3D training looks like it would be better for learning and also a lot more fun.
