Google Glass is still very much a work in progress. A few thousand people will get the device soon, the experimental "Explorer Edition," and Google is expected to make it widely available by the end of the year.
But for it to have any chance, it's going to need a lot of polish out of the box and for developers to support it.
This is why, even as it kept the public mostly in the dark, only releasing a few details, it has already started working with developers with the Mirror API.
In fact, after a few rather secretive sessions, Google spilled the beans in a 50-minute session at SXSW. In it, Google went through the Mirror API, the API for the Google Glass, and detailed its ideas for the device.
The talk by Senior Developer Advocate Timothy Jordan is titled "Building New Experiences with Glass."
