Here are my slides from my presentation on Gremlin's Anatomy: https://www.slideshare.net/StephenMallette/gremlins-anatomy-88713465
I plan to write up what was discussed there as part of TinkerPop documentation at some point soon. I think there are ideas which can be expanded upon and will be helpful to folks, so I'll see how quickly I can get to doing that. Thanks to those who attended - it was a good time.
