 * Yes, that was rather hasty of me -) I like the idea of having some standard clip art to use; it'd give a nice level of consistency to crypto articles. The reference site you gave me has good ones; I especially like the meat grinder for hash functions. John Savard's site looks like a wonderful resource - we should get him into Wikipedia! The M-209 looks like it could be a great challenge, but it'd likely require a lot more reference material than is readily available on Google. Ideally, I'd have a replica sitting next to me to model from; I'll peek around the web and see if I can turn up anything useful, though. If you know of any books I might find at the local library that would aid me, let me know. For now, I'll see if I can put together some basic clip art, and see whether I can wrap my head around AES before trying to illustrate it.
