If you are looking for medical help one of the first symbols you look for is made up of two intertwined snakes wrapping around a staff with a set of wings. This is know as a "caduceus" and has been mistakenly adopted as the universal symbol for a medical professional.

Historically speaking, the "Rod of Asclepius" should have been the layout. With it's one snake wrapped around a staff it should be more prominently "associated with healing and medicine" and is in some cases.

In order to keep everyone happy we have included all of the parts to make either symbol in one project. They are not limited to that, so have fun hacking the models together with ones in other projects or models in your library.
