People seem to forget that "electrical" effects predate digital computers. Cathode rays (before and after television) create "high-tech" animated vector-drawn images using analog systems to move the tube. Laser light shows are another example. The original digital raster graphics were worse in some sense than the analog vector graphics that predated them.
