I saw the 2009 Star Trek last night. There's a scene where young Vulcans are having knowledge fed into their brains at high speed; a montage, if you will. Some math formulas flash by, but then (as I recall), the words "Non-rival" and "excludable" flash on the screen.
If you look closely at Paul Romer, you will note the almost imperceptible pointy ears.
EDIT -- I deliberately wrote that without Googling whether what I saw was right, but Salon covered it as well.
