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 — it usually has lots of different angles and locations from which it can be viewed. 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.
