Repetition with variation is a common aesthetic concern in many art forms (music, painting, dance, theater, film, etc.). Presuming interaction(s) include, involve, or are entirely constituted of actions, we can ask questions about how actions might repeat with variation. This would provide a fairly traditional question for analyzing an otherwise novel form (interaction). How then can actions repeat with variation? What is it to do the same thing but differently? Below is a start to exploring these questions.
