Clappers for dummies

I wish everything I own had a Clapper so when I lost something, and I lose everything, I could clap and it would make its whereabouts known immediately. Of course, my possessions--counting books, records, socks and other things I own several of--number in the thousands, maybe the tens of thousands, so each possession would have to have a unique clapping pattern. I would have to keep a list of clapping patterns. And I'm sure I would lose the list.
