As this books hasn't been translated into Japanese,
I reluctantly started to read it in English.
And finally I finished it!!! John Maeda, a professor
at the media labo in MIT, writes about "simplicity".
Althought the volume of the book itself it not so big....

...Difficult! So difficult!

He uses a lot of examples of product design
such as iPod or B&O, but some of stories are
rather phylosophical matters based on his life experiences.
Well, my English ability is not good enough, that's all

He says:

"Simplicity and complexity need each other."
"What lies in the periphery of simplicity is definitely not peripheral."

and so on. Actually what this book talks about is very comlicated,
deep and it could be written in some thick, series of books,
but they are simply organized in 10 laws here.
But the impression after reading is so much.
I think it's great this book itself is following the laws.

mple design" tends to be so cheap,
but the reason why professional designed simplicity
looks so cool might be because they are following
these kind of laws. I felt like that.

He also writes blog about it.
