An introduction to the development of software applications for Google Glass (Glassware) using the preview version of the Glass Development Kit extension to Android. To illustrate the GDK, we have created a sample application, called Breaking Glass, based on the awesome TV series Breaking Bad Video of the presentation: https://www.youtube.com/watch?v=pV2_HjZk1W0 Code available on: https://github.com/everywaretech/BreakingGlass
