We can use the 'Sequence' command to generate a list of objects based on action applied repeated to the same object and can be described in terms of a counter n.[br][br]In the following example, the action of rotating a triangle (poly1) is repeated 10 times, generating 10 images:[br][br][color=#ff0000]Sequence[Rotate[poly1, k*t, A], k, 1, 10] [/color][br][br]In this command, the letter k is used to indicate how the angle should change from the first to the last (10) image.

This is a similar example showing result of repeating dilation on the same object:[br][br][color=#ff0000]Sequence[Dilate[poly1, r^k, A], k, 1, 10][/color]

Finally, a spiral pattern can be made by generating a sequence of images from rotation and dilation at the same time:[br][br][color=#ff0000]Sequence[Dilate[Rotate[poly1, k*t, A], r^k, A], k, 1, 10][/color]
