Today I found this new book in a bookstore in Shibuya. Omnibot Fan Book, published by Mycom, has been written by Techn'o'taku a famous Japanese otaku who loves design, techno and toys.  The book covers the history of toy robots from the early sixties to the just released i-Sobot (that's the natural evolution of the Omnibots produced by Takara Tomy more than 20 years ago).
In the next few day will try to take some photos of the beautiful designed pages of this book.
