If you're anything like Minister of Propaganda Karl Marxxx who recently fell in love with his first iPhone and its many enticing apps, most remarkable among them the personal assistant app Siri (Speech Interpretation and Recognition Interface), you may also like SHIRI, a robotic ass that responds to a "user's touch, stroke or slap" in predictably human ways-- "bracing" for instance, from a firm spank of the hand. Japanese engineer Nobuhiro Takahashi, developed SHIRI using "a rigid urethan skeleton, a life-size model pelvis and a Gluteus Maximus Actuator (GMA)". In an oddly phallic gesture, the butt inflates with air and "protrudes" when stroked. While the perfect gift for any spanking enthusiast, it's a shame SHIRI's silicon skin doesn't leave handprints. That's the best part of all.
