TV Set Doubles as a Mirror
Bill Kendrick writes "New Scientist reports there's a new wide-screen LCD from Philips which becomes a mirror when you turn it off. Now I just need that holographic fireplace..." Sorry - a dupe from June

They claim to have a patent on the holographic fireplace. I don't see why something like this couldn't be made.
I also though of the recent "geek retro future" version of monster house where they made a a giant fireplace with stainless stell remote controlled opening doors and mounted a Plasma screen above it. Tres cool.

Further to the answers already here, static electricity is indeed why the paper sticks.
The reason that your screen charges up is because at the back of your set there's a bloody great electron gun (three if you have a colour TV) firing countless electrons at the back of the screen, which are deflected with a magnetic field in a neat pattern that creates the image.
Electrons are negatively charged and over time they cause a charge to build up on the screen.
As an offtopic point, the electrons hit the phosphors on the screen, or pass very close to them which causes them to glow, which is how a TV works. The electrons already present in the phosphor atoms change energy states, which releases light of a characteristic colour (either red, green or blue in the case of a TV).
