Hm? Oh. [Right, other actual person. Tony glances briefly over at him, then beings to point out bits of the design as he talks.]

It's kind of like a prosthetic, only not full limb replacement, obviously. It works as a brace for balance, but uses a little bit of power to guide movement and make it easier. The -- guy I designed them for, he can't walk at all without them, so the current design is probably a little intense for you. But I can tweak it.
