University of Iowa in SL

Today I was talking some collaborators on LLL3D about how to visualise concepts in Second Life.
I remembered I had seen some twitterers mentioning that the University of Iowa had a visualisation of Bloom's taxonomy, I did a search and found that they had interactive models of both Bloom's taxononmy and Wenger's Communities of Practice.  

Bloom's Taxonomy

 Wenger's Communities of Practice

The models were freely available so I picked up copies. I wonder if learners found the models a useful learning resource, or if the more powerful learning experience was creating the ideas for the models.
