Have you visited Japanese shrine?  If your ansewr is yes,  I guess you have seen the pair of spluctures of liondogs or masclemen on the both sides of the gate or the entrance.  One of a pair whose mouth is open is called the form of " A ",  and closed is called the form of " UN ".   " A " means the begining of the universe, and " UN " means the end, orignally .  Then the word " AUN " has more familir meaning, is used to express the good combination.    I drew a person talking to someone. And one more listening to somebody.  Naturally each tittle was desided.   My ' A ' of ' a-un ' was made in just time for the bigining of the first Setouchi Triennale.  And it's located on an alley entrance. And when you walk 55m (180ft.) ahaed, ' Un ' of ' a-un ' appears on the closs-point with another alley.    How will you feel the chatting between ' A ' of ' a-un ' and ' Un ' of ' a-un ' ?   I'm looking forward to it.
