So the “Flash Forward” viral commericals continue during LOST. Actually, I only caught one, but part of the time the tv signal blinked out, so I may have missed some. It looks like they put up several images. The only one I was able to see & remember was a dog.
I googled “What did you see” and the very first site was:
What Did You See?
With the following tag: Help Put the Pieces Together.
My first post on the subject is here.
Life & Love & Why 
“Flash Forward” is new TV series based on Robert J. Sawyer’s SF book of the same name. http://www.sfwriter.com/exff.htm Book’s premise was interesting. Let’s see how well they execute.
