BioDigital Human

Ran across this today while checking out some apps for chrome.

It’s an anatomical human in digital form (male and female)
This is a great tool for digital artists especially for those learning or needing reference for the human forms many structures.

Has basic camera controls and a nice visibility toggles in a collapsible tree to control what is displayed.
There are also a couple display modes, x-ray, and isolation (in case you only want to look at a single muscle or bone)
