You've gotta give it to Japanese erotic game developers. They sure are inventive! PC title Hypnotism Class lets players hypnotize schoolgirls.

What does this do? It causes them to stand on their heads, it seems. The girls, however, continue to converse — however, a different (and novel?) view is provided for viewing pleasure.

It's even possible to suspense these girls in "headstand mode" for the rest of the game. This is either creativity at it's worst or at it's best. We really don't know.
