Just a thought I throw out for consideration and response.
One of my other hobbies is railway modelling (not that I get much done) and one of the groups I follow have been sending a wagon round, photographing it on the various layouts it visits.
I wondered if there would be any interest in my sending out a figure (54mm, Victorian) to act as Military Observer at various sites occupied in Funny Little Wars style operations. If I were to send him to the first, he could be photographed in some situation and passed on to a site of visitee's choosing, and so on, eventually returning to me. His progress could be followed through the various blogs, and I could keep a diary running as to where he is.
