Corey sends in his own tattoo collage of geekiness. He explains:
It is a very simple Hillis Plot (also called a Circular Tree of Life) with the word Reason over it. The tree depicts the evolutionary history of speciation, and how all living things are distant cousins of each other. The A is red as a nod to the scarlet letter and symbol for atheism (you can’t condemn me for something I wear with pride). There is a red line as part of the plot to show where mammals fall. I got the word Reason, because it is something that I try to apply to all areas of life.
He designed it himself and got Fredo over at Foolish Pride Tattoos to ink it.
