The answer is, take control of the lightshow yourself. The LanBox-LC II can be synchronized using MIDI, a serial cable or from any computer. The LanBox-LC II is highly portable, designed for 'on the road' use and can be installed on any solid surface. Combined with a laptop computer you have your portable lighting control center, and you finally have lights exactly when and how you want them. People visit museums and other places of exhibitions less often than they used to.
Broadcast television keeps people at home, in their comfortable chair.
Still you're convinced that your museum has something more to offer than a cathode ray tube. You need to make people become awed again, capture the magic of what your showing and give it to the people. An impressive presentation does not necessarily mean making a noisy, obtrusive show. Lighting can be used subtle, setting moods, creating atmosphere. Classic theatre plays by Shakespeare are performed with lots of lighting effects these days.
