A range of new technology is entering the special effects business, some of it coming from aerospace concerns which are looking for new markets. New technology includes computer control systems and linear actuators, which give improved control over the equipment and thus allow the effects to be staged closer to the audience. There are now attractions which link simulators with elements of dark rides, and it is possible to create an entire environment.
