When I first saw Alien, I loved the exoskeleton Ripley wore in her battle with Mama Monster. Some folks in Japan have now built it, and not just as a prototype, but as something you can use in emergencies or on a construction site. It would also form a worthwhile core for a good Giant Mecha suit, getting us one step closer to that reality as well. Thanks to Crunchyroll for the heads up on this one.
