Student Actively Involved:
- This application is interactive. The student does not passively observe it; he or she designs the experiment, runs it, refines it, runs it again, . . .
- The result of the experiment can be saved and shown as a movie to another student, or to the instructor.
- The default number of 2000 mass points connected by 1999 springs can be reduced, and convergence to continuous string behavior can be observed.
