Tendril Vision Clock Helps You Save in Electricity Bills

I like the Tendril Vision's looks. And I like it even more because it's real, even while it feels like a spare part for the Enterprise's bridge. The clock connects to the electric grid, giving you real time consumption information.

The device shows usage information, and also displays the cost of energy during the day, allowing you to run appliances whenever the cost of electricity is lower. [Tendril via Earth2tech via Treehugger]
