Those who already own Google Glass are more likely than most to embrace new technologies like Nest's thermostat, so it only makes sense that an especially eager adopter would find a way to combine the two. That would be James Rundquist and his new Glass Nest app: Glass owners now just have to announce that they're coming home (or heading out) to make their Nest units change the climate. More exacting homeowners can fine-tune the temperature, too. While the utility is both unofficial and quite limited at this stage, Rundquist has posted source code that lets anyone expand on the project. If you're in the rare position of owning both gadgets, we'd suggest giving Glass Nest and its code at least a cursory look.
