This article presents the authors' personal accounts and their experiences in working on mathematics using "arms." "Arms" is an idea that first appeared as a program written by John Warwick and David Wooldridge in an ATM publication "Some Lessons in Mathematics with a Microcomputer," 1983. The introduction to "Arms" in the book states that it is a program for the study of locus. It goes on to say that two rotating arms are displayed on the screen, the tips of these arms are joined by an invisible elastic band on which a dot is marked. As the arms rotate the path of the dot is plotted on the screen. Here, the authors split their attention between working on the mathematics and paying attention to how it was being worked on by the group.
