Keep tabs on your consumption

You're feeling pretty good about yourself these days. Walking to work? Check. Cycling around town? Check. Recycling bottles and cans? Check.

But if there's a nagging feeling that you could be doing more, then here's the device to help you maintain that guilt complex. The Manodo Display from a startup company in Sweden puts green habits to the test.

The device gives household residents all the facts about how much and what is being used, right down to the number of pounds of CO2 emissions from your last bath.

Imagine having Al Gore living in your house reminding you each time you forget to turn off the lights! The intent is to keep residents aware of how much resources are being consumed through daily activities ... and maybe guilt them into changing their ways.

The monitor also provides current information like the weather and when the next tram is scheduled to arrive at the nearest stop.

Now being tested in the hallways of 15 apartments, the Manodo project isn't all about negative feedback. When good green levels in the apartment are reached, a green smiley face appears on the display.

How else are you supposed to know if you're a good person?
