Yappyfox ran a ham radio tracking contest at FWA and asked if I could hide one of the three trackers on my table for people to find. The object in question was a "fox", but at least in my case it was a literal fox, -a tracker embedded within a stuff fox toy. The item was hidden in plain view on my table but only those people with the necessary ham radio equipment would be able to locate it. The prize for locating the fox was a picture from me of their personal character, and this was the result.
