Otaku guys have been kissing posters of Japanese pop idols for years, but now the posters are kissing back.

A research group at Keio University used ultrasound proximity sensors to create a digital poster of an idol with facial expressions that change as the observer gets closer. Put your face right up to the poster, and she goes in for a kiss.

We think we could get pop idols to actually pose for this, and sell it as an application, or it could be used in digital signage," said researcher Keidai Ogawa.

Now all they have to do is add the kiss transmission device from Kajimoto Laboratory, and they'll be in (really creepy) business!
