Design a concept range of thermostats

This project is to develop a conceptual range of thermostats. We are looking to develop styling ques and design ideas which can apply all the way from premium internet connected thermostats down to low cost thermostats. After this conceptual range is complete, there will be further projects to develop actual thermostat products. This project is for the US market, so applicants must be able to demonstrate experience and knowledge of design styles for the US consumer electronics/ home products market.
