I went to South Street Seaport yesterday to check out the Bodies Exhibition.
These are human bodies and parts preserved with an acetone polymer, which replaces all the body water with plastic. It was excellent. A really cool experience and I learned a ton about anatomy.
Check out the videos at the site ::
It was a work of art as well as science. All the systems were there, and they way they preserved the circulatory system was amazing, as well as bit surreal.
