As a medical student, I studied a slide tape demonstration of inguinal anatomy and hernia repair over and over again. Hours of study led me to eventual mastery of this color-coded inguinal canal, knowledge that I have retained but never used in the ensuing decades. Early multimedia tools such as these have been superseded in medical education by elaborate computer-generated graphics and animations. Similarly, courtroom demonstrations of injuries and accidents have advanced from photographs and poster-sized drawings to frequent use of custom computer animations.
