In ABC's new speculative fiction series FlashForward, the entire world blacks out for 2:17 second. During that time, everyone sees a vision of the world on April 29, 2010.

Visistors to the floor of Comic-Con International can visit the FlashForward booth and share "what they saw" during their glimpse into the future for The Mosaic Collective.

Obviously, it's all part of the make-believe fun here on the Comic-Con floor. The overheated crowds haven't started blacking out yet. But, this kind of audience participation is a key marketing theme around here.

Would-be fans of the show go into portable recording booths and put to video whatever they make up about their "vision." That recording is then put into the visual archive ABC is building here.

I'll have more from the floor as the convention continues. Meanwhile, panels for the top shows begin here in a couple hours.
