Are you thinking of something like the old police identi-kit that would allow an eyewitness to select from pictures showing a variety of noses, eyes, mouths, hair, etc. to create a facial composite?
If so, it sounds like a better candidate for an interactive webpage/app than the wiki.
If you're thinking about using the diagram to describe the parts and functions, the
new FAQ and "Main Arcade Cabinet Portals" on the
main page both cover similar ground -- we still need to sort out the best way to organize and present the info.
You're welcome to sign up for a wiki login and throw in your $.02.
