I recommend a hilarious book called "Play with your Food", a (mostly)
photo essay in which fruits and vegetables suggest facial expressions.
It gives some historical info on Giuseppe Arcimboldo, the sixteenth
century portrait painter who assembled food into portraits. (Look into
his Four Seasons series, it is fascinating)
The author of the book is Joost Elffers, published by Stewart, Tabori
and Chang, 1997.
