I would like to play with Google Glass API but it's only available to developers who have Glass as part of the Explorer Program. I missed Twitter contest too.
If you don't own Glass, Google currently will not let you have an API key.<p>However, this guy has been working on trying to replicate the API as closely as he can though for those who cannot get at the real deal.<p><a href="https://github.com/Scarygami/mirror-api" rel="nofollow">https://github.com/Scarygami/mirror-api</a>
