Years ago, I wrote a book of essays entitled "Turn Signals Are the Facial Expressions of Automobiles." Didn't sell well, so now it is out of print. But, hey, some people remembered it: "In 1992, the usability guru Don Norman wrote that every child should receive a personal teddy that would store all the experiences people ever had." said the Sydney Morning Herald.
(You can find "The Teddy" -- and other chapters from the book in the books section of this website.)
