Vincent Van Gogh's Paintbrush is the Disney film artifact.

To an extent, all psychological artifacts induce "madness," which was a blanket term even during it's heyday, so it is generally better to specify what sort of perception warp the person is experiencing. Like if you were to do the tea set of the Zhengde Emperor, for instance, it could regress them to act as a spoilt child. If you wanted them murderous, there's always Catalina de los Ríos y Lisperguer.
