No one seems to appreciate gears more than a Hollywood cinematographer.

Interesting gear factoids discovered wasting time on the Net while pretending to be working...The first four-function mechanical calculator was built by the mathematician Gottfried Leibniz in 1694.

In our unceasing attempt to further educate our readers - and find new and creative ways to waste time at work - the Addendum staff has spent many long hours (and many dollars on popcorn) to bring you our latest research on gears in film.

Gear Technology's bimonthly aberration - gear trivia, humor, weirdness and oddments for the edification and amusement of our readers. Contributions are welcome.
