my family and i attended the body world 2 exhibit in san jose over the holidays and highly recommend it if you're interested in the understanding and seeing up close and in great detail how the human body is built and functions.

my understanding is there is another, similar exhibition making the rounds but rather than the exhibits - which are called "plastinates" - being voluntarily donated specimens (by the humans used in the exhibits, themselves), many of them are the bodies of executed prisoners and derelicts who were sold to the company for use in their commercial show.
