"The Structure Sensor has been designed to be the perfect hackable sensor. We will be hosting open source drivers (http://structure.io/developers#drivers) and CAD specs (http://structure.io/developers#brackets) for the device itself, and we've even created an optional Hacker Cable to let you easily add the Structure Sensor to almost any platform."
