Contemporary theaters are often non-traditional, such as very adaptable spaces, or theaters where audience and performers are not separated. A major example of this is the modular theater, notably the Walt Disney Modular Theater. This large theater has floors and walls divided into small movable sections, with the floor sections on adjustable hydraulic pylons, so that the space may be adjusted into any configuration for each individual play. As new styles of theater performance have evolved, so has the desire to improve or recreate performance venues. This applies equally to artistic and presentation techniques, such as stage lighting.
