Guests will gladly get in line for Dance Heads, a new entertainment concept that uses “green screen” technology to superimpose guests' heads onto professional dancers' bodies. Up to three people at a time sit on stools and are covered up to their necks with green spandex as they lip-sync to hits such as “I Will Survive”; a digital recorder captures the performance, which is then transferred to software that places the heads onto dancing bodies in front of animated backgrounds. The resulting effect is highly entertaining, even to people watching the process as they wait in line. Each guest receives a VHS tape of the star performance.
