One thing to consider when programming for a permanent installation is the perspective of the audience. First, there are the multiple viewing angles. Rarely does an installation have one primary audience location. As you program, and once the installation is completed, you should try to view the results from as many different locations as possible. Only then can you assure that everyone viewing your work sees what you intended. Second, you need to consider the venue. When I recently did some programming in a restaurant, I carefully positioned fixtures so they were not pointing into people's eyes as they walked around the room. Not only that, but I had control of all the lighting in the venue; I had to maintain levels so the guests could see their food and walk around safely. Third, you should consider the purpose of the lighting. As with any show, you do not want the lighting to upstage the experience of the venue.
