Paddywhack!'s mechanics are in all likelihood the most
intricate ever created in a movable book, surpassing even those
of the legendary Lothar Meggendorfer (1847-1925).
Andy came to paper engineering from a background as a tinkerer
and repairer of antique record players, radios, automobiles
and other mechanical and electrical devices. He is based
in Santa Fe, New Mexico.
Paul Zelinsky's collaboration with Andy was trans-continental--
a monumental effort, involving many hundreds of hours of
telephone calls, a similar number of e-mails, and a considerable
amount of overnight shipping. The collaborators started and
finished their work on Knick-Knack Paddywhack! without
once meeting face-to-face.
However, both continued their
involvement in the project to the point of overseeing its
printing and assembly. It was in the city of Shenzhen,
China, where the two met for the first time.
