document: A server-side program for delivering experiments with animations A server-side program for animation experiments is presented . The program is capable of delivering an experiment composed of discrete animation sequences in various file formats , collecting a discrete or continuous response from the observer , evaluating the appropriateness of the response , and ensuring that the user is not proceeding at an unreasonable rate . Most parameters of the program are controllable by experimenter-edited text files or simple switches in the program code , thereby minimizing the need for programming to create new experiments . A simple demonstration experiment is discussed and is freely available
