Assassins in Assassin's Creed hide spring-loaded blades in their sleeves, to devastating effect. Want to learn the second best use for an assassin's hidden blade? Well, look no further than the apartment, er — workshop — of Japanese inventor Shota Mori.
In development since 2011, the iSleeve (or whatever you'd rather call it) underwent major redesign and improvement in late 2012. Early missteps concerning iPhone ejection have been smoothed out, which is pretty important. The 2012 version, you will note, only seems to fly out of the inventor's hand once during the filming of his amazing demo video below. It also seems that he's created at least four prototypes.
Now, I can't quite tell whether it's the sheer awesomeness of the invention or the intrepid inventor's non-traditional demo video that's sold me. All I know is that I need one of these. And maybe a papier-mache head for my desk.
