faketv led screen simulator in action

Is this the same size as normal tv?

no. Smaller

Nice idea.

That is awesome!

Although the home invasion robbers would be disappointed to find you AREN'T home and just steal this, along with everything else.

The first thing that comes to mind is that it's used to make people think you're home when you're not. sort of like leaving a light on a timer.

"simulates the seemingly random patterns displayed on a tele" so... what is this good for?

if you're not home it would keep the thieves away;) As they might think you were watching television:)

It says "keeping prowlers at bay"

You turn it on while you are on vacation so someone thinks you're home. The glow it emits looks like an illuminated television screen. It switches patterns to simulate color changes in the screen (to emulate the ever changing images on a TV screen).

Also, it saves more energy than simply running a TV while you are away. It's more cost effective.

Saw this on the telly, gadget show :P
