As we did with the former pair, let's examine each of these individually. Run this display by first by clicking the Action button 10 times to see the scope of the spin transform and to end up well away from the origin. Note that the spin transform includes an x displacement to expand the circle.

Next, select the shrink transform using the Change button and click the Action button several times to see where it goes. At this point you may experiment with the two transforms through manual selection to get some feel for the possibilities. Just shift back and forth between the transforms trying various sequences.
