Ono created the concept for the book in 1996, when she was experimenting with
digital art. It was inspired by a 1969
Fluxus by
Plastic Ono Band, a group Ono and
John Lennon were members of, in which they had planted
acorns at
Coventry Cathedral for peace. Subsequently, they mailed other acorns to world leaders with a note: "Enclosed in this package we are sending you two living sculptures—which are acorns—in the hope that you will plant them in your garden and grow two oak-trees for world peace." ==References==
