It's what I've been calling an 'activity board', although I like @CYOA's 'busy board' more. Basically something for little kids to play around and interact with. I think that kids see adults using door handles and locks and light switches and want to do the same. I'll build this and he'll be no more interested in it than any of his other toys, and will still be happier playing with the fixtures and fittings around the house...
what is that thing you are building?
