What did you see? :O?

i was watching lost last night, and there were these eerie commercials where it flashed a tiny little clip of something, then it went away, displaying in creepy writing "what did you see?" there were a total of four over the hour of lost, and they were different things, first was a marriage, second was a surfer surfing a wave, third was a baby in the womb, and the last was children getting out of school.. i went online and google'd ittt, and it came up as a sight with just those words, "what did you see" and at the very very bottom it said the mosaic collective, does anyone know what this is? its creeping me out..
