We are often asked "why Scala?" The answer is usually that Scala is one of the few viable alternatives to video production. If you bracket dynamic visual communication with traditional television video production at one end, and advanced interactive multimedia authorware at the other end, then Scala lands somewhere in the middle. Scala producers need not be video producers or computer programmers. Instead, they are expected to be reasonably competent graphic artists with a sense of timing and transitions. The resulting Scala visual creations are dynamic and effective alternatives to video production and complicated programming. Scala is perfect for the emerging field of digital dynamic signage based around advertising and plasma screens.
