They will communicate through the shoal to a floating hub via flashing LEDs, relaying information on conditions such as temperature and salinity. Video transmitted by mobile phones is usually too sluggish to allow people to communicate effectively by sign language. Now software developed by a team from the University of Washington in Seattle selectively compresses the video data,
