LOST ON THE FRINGE
In the most recent 'Fringe' episode, "The Man From The Other Side", a known crossing from the alternate TV dimension (apparently being dubbed "the Walternate Universe") played hob with local TV signals. And somebody in that area was recording the frequency at the time.
The dimensional blip lasted only seconds, but the good folks at FringeTelevision.com were able to snare the relevant images from the broadcast....
TV ON THE OTHER SIDE
Several of those shots are pertinent in pointing out the differences between the two dimensions - the glass dome of the White House, the number of stars on the flag - but the 'Lost' frame grabs would appear to be a Zonk.
It's O'Bvious why they were chosen - despite his involvement being in name only on 'Lost', JJ Abrams is the executive producer of 'Fringe' as well and they probably thought it would make for a cool in-joke. (If I remember correctly, there was also a reference to 'Star Trek' that episode.)
But it makes for a Zonk as far as Toobworld goes unless we come up with a splainin. And this is all that I've got: The scene showing Greg Grunberg and Emilie De Ravin was of their characters "the Pilot" and "Claire" - but it was airport security footage somehow picked up and transmitted by the interdimensional anomaly.
If you have anything better, I'm willing to consider it....
BCnU!
