I came across this a week ago and think it's the most brilliant item for the home:
Nest - the learning thermostat (
www.nest.com)
It could also be controlled through WiFi from any smartphone, laptop or tablet. The more you use it the more it knows your habits and temperture settings, and it generates a monthly energy report. You could also change the colour of the LCD display.
It's a little pricey at $249/retail, but your energy savings will pay it off in no time and it just looks cool. No moreboring putty grey thermostats on your wall.
