Who is Grok?

Grok is a friendly caveman from the Stone Age.


He has a big club that he hunts mammoths with. He will also use this club to smash anything he doesn't like.


The word grok comes from the novel Stranger in a Strange Land by Robert A. Heinlein, and is defined in his book as:

Grok means to understand so thoroughly that the observer becomes part of the observed - to merge, blend, intermarry, lose identity in group experience.
