Not said, per se, but the tattoos have been featured in cover art. Notably, the cover for Chapter 27 and the infamous TOWTM bust picture.

I, along with the help of several luminaries here on the forums, have done considerable analysis, conjecture and theorizing on the nature and meaning behind the tattoo; here in the theory section of the forum.

While we have been able to assign possible meanings to individual segments... we really haven't been able to cohesively tie it together. It is as if we have been given a jigsaw, but there are several puzzles in the box, though we don't know how many and there are a lot of pieces missing.

A formula you say? Have a look for yourself. Buckle up first, you're about to go for a roller-coaster ride down the rabbit hole.
