A research group at Keio University has developed an interactive poster that loves being kissed.

As one gets closer to the screen, an ultrasound sensor picks up the movement and changes the image on the screen from a blushing girl to a girl with her eyes closed and ready for a big smooch. If one backs away from the screen, the image changes back. The research group has also considered adding a smell element that would include the scent of shampoo. They've also thought about adding a speaker that whispers "I love you" after the kiss has been given.
