Gears And Glory

Good fellows of this institution, I am in need of instruction. I find myself drawn to the use of my difference engine in the creation of detailed pictorial representations of geared devices. I would be most grateful to any and all able to recommend, and indeed direct me to, repositories of knowledge pertaining to the expedient production of beauteous images composed primarily of interlocking or solitary brass cogs, clockwork and related items.

Most particularly, instruction in the efficacious application of the GNU Image Manipulation Program would be heartily received.

My thanks in advance.
