Fake TV

There's an energy efficient device called FakeTV that's a burglar deterrent. It makes it look like you have a TV on in the house but it's really just an array of LEDs. They have an assortment of good arguments for why this is a good product. It's good to use when you're home alone or out of town. I only saw this recently and thought it was cool enough to share on my blog, so check it out.
