Might be an idea to replace the included (one year lifespan) CR2032 battery with a rechargeable one. And also include (embed/hack) a wireless recharging module in the base?
Otherwise, in a about a year, you're going to get the notification that the battery is running low. After which, the sculpture will no longer be trackable.

I could see it potentially being used to track for anti-theft purposes while it sits on a shelf or table at say a booth during a festival or something like that. The person selling it can just deactivate the AirTag after the item is sold. Could make financial sense for higher end items.
