Looking for something that a grandmother could use to scan a bunch of pictures, and then later process them on a computer after retrieving the memory card.

Color raster scan computer graphics was born! A separate memory plane was sometimes used to provide a cursor, so cursor movement could be made independent of the image of primary interest.

The early days of computer graphics, when they had to be mixed with real life, often produced some of the most memorable results. The Utah Teapot is one such example, Jurassic Park is another.
