Iteration Animated Applet
Here is an applet that demonstrates the execution of a small program which draws a circle as a bunch of points equidistant from a fixed point. Watch how the program gets executed, step by step. Especially watch how repeat's count gets decremented after each time its List-of-Instructions is executed.
