How about an app that can check facts in a news article as  efficiently as spellcheck can flag errors in a document?  For example, suppose Bush Era Republican Eric Cantor pens an op ed piece.  All you would have to do is click "select" on the whole piece and the app would automatically highlight factual errors, and offer corrections.  You could customize the app so that when it finds a complete falsehood,  it plays Lies, the 1983 song by the British pop / new wave band Thompson Twins.  You should be able to download the app on your mobile phone and in preferences, choose "voice-activate".  So that if you're at a press conference and Eric Cantor is speaking, your cell phone will automatically blare the "Lies" song when Cantor spouts a doozy.  More of a visual person?  How about a holographic projection of LL COOL J LYRICS That's A Lie?  Choose from 1000 different 3-d typefaces!
