Carnival Cruise Line said the computer-controlled Dreamscape art installation in the atrium of the upcoming Carnival Horizon will use images created by patients at St. Jude Children’s Research Hospital in Memphis.  The Dreamscape, a three-deck centerpiece in the Horizon’s atrium, will feature 33 artistic creations from patients of St. Jude, one of Carnival’s largest charitable partners. The 24-foot funnel-shaped centerpiece that debuted on Carnival Vista is comprised of more than 2,000 flexible LED tiles that have been customized for the shipboard environment. Each day, technicians program the rotating artwork based on the time of day, port or occasion.  For Carnival Horizon, the young artists were asked to create fun pieces with bright, bold colors showcasing their personalities. The Horizon’s maiden cruise departs April 2.  Founded by entertainer Danny Thomas, St. Jude’s opened in 1962 with a mission to find cures for childhood cancer, sickle cell and other deadly diseases.
