Tha 666 Logo

A sketch/start of my 666 logo.

The logo is build of three sixes, the sixes form a graphic stylized digital circuit of the smallest tautology in the one operator boolean base {nand}, which is one of the two smallest boolean bases: the term x(xx) (operator implicit).

A tautology is a term which is valid for all assignments of propositional variables. The logo stands for "the truth."
