You have 12 hours to kill on an airport layover... why don't you, well, make a movie?
Richard Dunn did just that when he was stuck in Last Vegas McCarran Airport. An amateur filmmaker, Dunn shot a video entirely on his iPhone, edited it, then set it to Celine Dion's "All By Myself". Watch it, it's fab.
We love it! Best part: he's Canadian, eh?!
Not sure who could top this.... but what's the most creative thing you've done on a layover?
