Snell’s O & P has been in business since 1911, and Chris Snell is the fourth generation of his family to make orthotics and prosthetics. Chris recently made this steampunk leg that has gears controlled by a microprocessor and powered by movement. It creates the illusion that a presumably steam-powered set of gears is moving the leg! He also posted a gallery of some pictures taken during the building process. -via Geeks Are Sexy
