In effect, the X-stem Logic Alphabet is derived from three disciplines that have been stacked and combined: (1) mathematics, (2) logic, and (3) semiotics. This happens because, in keeping with the mathelogical semiotics, the connectives have been custom designed in the form of geometric letter shapes that serve as iconic replicas of their corresponding square-framed truth tables. Logic cannot do it alone. Logic is sandwiched between mathematics and semiotics. Indeed, Zellweger has constructed intriguing structures involving the symbols of the logic alphabet on the basis of these symmetries ([http://www.logic-alphabet.net/images/clockcompass_2353_2.jpg). The considerable aesthetic appeal of the logic alphabet has led to exhibitions of Zellweger's work at the Museum of Jurassic Technology in Los Angeles, among other places.
