Hey Everyone, there is a free online version of SKULL Graph you can use on your computer or mobile device - CGmodeling.com/skullgraph
I was having trouble remembering names of facial muscles and skull bones, so I sculpted them in ZBrush and created an App in Unity for anatomical reference.
Quick Demo/Tutorial
Well done! 
Great tool for artists

Very cool app. Thanks for letting us know about this and making this available. Great work, John 
Tritt, Jaime, John, thank you- I hope you find it useful.
The app has been optimized. There should be no more loading time issues, and is scalable in mobile browsers. I’m working on making the skull files available, and will post when I have them up.
This is really great! Thanks a lot for sharing it for free!
It’s a great help for Artist…!! Thanks for sharing
That is cool! I really like how you can hide all the individual teeth.
