My wonderful Patreon supporters get this model free :) Some models really do defy photography in terms of demonstrating what they actually are, and leave me puzzling over what angles really show how something works, or even what it is! The Sprocket Box is a good example, as is this one! It's a box, kind of, but perhaps it's more accurate to say it's an exploration of geared motion, or something like that :P Read the original Patreon writeup here: https://www.patreon.com/posts/45534836
