Sorry, I don't have a plan but it shouldn't be too difficult for you to design your own. You are, I presume, aware that the the man and woman are attached to a taut piece of catgut that twists and untwists with the changes in humidity?
These were popular in the days before central heating so I don't know haw well they would work in a modern, centrally heated, fairly airtight home.
You might get it to work in a kitchen where the bloke turns out when there have been pans boiling on the stove ie ready for a meal and once that has dissipated the woman comes out to do the washing up ad the humidity drops.
Might be a conversation point or a marriage wrecker?
