Be forewarned, the video above is full of boobs; boobs of all kinds, big and small. All of them moving slowly up and down in a  rhythmic motion - but enough about the dudes with the controllers in their hands.

Ninja Gaiden Sigma 2, we found out earlier this month, will utilize the SIXAXIS controller in ways that might just be illegal in a couple of countries. The YouTube video gives us the Japanese trailer for the game which shows that technology in motion, kind of. Unless the game is nothing but a pair of breasticles on screen, it would be nice to know where this interaction is happening and, shockingly, what the actual gameplay will look like with the tech in motion.

And if it will work with one hand.
