The roots of this idea go back 400 years -- but Martin Lewis has yanked it into the 21st century. It was worth the wait.--Max Maven. Precognition: Clairvoyance relating to an event or state not yet experienced. In this case to foretell a video event before it occurs. A spectator chooses one of six disks and places it into a DVD player. They then choose an episode on that disk, then a chapter from that episode. Before they hit the play button you describe a scene in detail. They then play their selection and it matches your description perfectly. The disks can be checked both before and after, all the episodes and chapters are different. The effect plays in almost any venue, from a TV set in a living room to a full size auditorium. If the theater has multimedia capabilities the effect plays huge. NOTE: This product is compatible with most DVD players, however there may be some off brand, or older machines, with which it is not compatible. Please check first.
