Scanners and moving head lights are great for creating effects over a large area. You can choose wash or spot depending on the size of the light beam you want. There are also effect lights called scanners that move DJ effects around the room. Most spots feature Gobos and color wheels that can create shapes of differing colors and combine these for a multitude of interesting effects. Sound active modes allow these lights to be plug and play effects of color and movement all over the room.
