Came across this on Twitter yesterday. Wish this resource was available when I was in college. A feature that might get overlooked is the search feature in the top right hand corner. Just start typing a body part and it instantly zooms in to that area just like the instant search on Google.
In the future, I would like to have more information on the actual parts. Instead of just identifying the parts, I would like a definition on what it does. In addition, I would like to be able to click multiple parts and create printable images. It would be awesome if I could select the muscles that are trained with certain exercises and create posters for them.
I have to anticipate that new features will become available. Google is great about releasing Beta versions of everything and letting real people refine their products.
