Remember that trick the Gizmodo kid pulled at CES? Its called TVB Gone. It was a horrible trick but very funny if you were not one of the people that paid for the CES sponsorship.
I wish though someone would invent Cell phone be gone. Lots of rude annoying people in lots of places, can suddenly be silenced with a nifty “cell phone coverage blocker”. Zap the calls into oblivion. Please someone invent this.
