We Have Lift Off

Japan is famous for many things, one being their perverted ways. Over in the land of the rising sun, there is an erotic game (yes they play those there) that can somehow detect once the player gets an erection. Details are scant, as they are mostly in Japanese, but it uses a webcam with facial recognizing technology and little Japanese magic to know once lift off has occurred. Ah, we really are in the future.
