I once painted the entire souterain of a large home in Canada. It started out as the owner just wanting me to paint some grapes above his bar, and then he would not let me stop until I painted several rooms, including the ceilings ..... Just recently my oldest son was wondering if this still exists, because the home changed owners (likely several times, since the original owner died decades ago).
It may not be every ones taste: some of it was (and that was his taste) looking more like a Reno brothel.
