Some additional words on "Ninomiya" and "Cat" to non-Japanese users.

You find "Bar", "Kiss !", "Toilette 1" and "Toilette 2" easy to understand.  And perhaps you may be tolorent enough to accept "Mr. Kinoshita".  Yet, most non-Japanese users will find "Ninomiya" and "Cat" unknown.  I would like to add some words on them.

"Ninomiya"
Mr Ninomiya is a historical person in the Edo era.  He was a specialist of agricultual policy.  
He was born to a poor family, and he had to work hard to support his family's life.  He served a wealthy family, and his primary duty was to collect firewood.  
He was an industrious boy who loved to study.  It is a famous story that he kept reading books even while he carried firewood on his back.  Thanks to such industriousness, he became very smart, and later promoted to a minister.  Born to a poor family, he never fail to think of poor peasants.  He tried to save them by encouraging technical improvement of agriculture.
Until a generation before, it was a common custom in Japan to put the boy Ninomiya's statue (especially reading books with firewood on his back) in primary school.  He was regarded as a symbol of hard-working children.

"Cat"
I know that everybody knows cats.  But this "Cat" is special.  Look at the blank icon carefully, and you will find that the cat has its left hand up.  This is a special image of cat called  "maneki-neko", which is said to bring good fortunes.  It is popular, especially among shop mangers, to put statues of the "maneki-neko" at their houses, their shops, etc..  
Some "maneki-neko" has its right hand up.  Some people say that the types fortunes the "maneki-nekos" will bring are different, according to the hand they lift up.  I am not very sure of it.  Anyway, the "maneki-neko" will certainly bring some kind of good fortunes to you and your Macintosh.
