Spiral Crosses - a rotation and dilation exercise[br]Use slider n for number of iterations[br]Use slider r for rotation in 0.001 increments [br]Use slider d for dilation in 0.001 increments [br]Build command structure in 3 steps:[br]Enter Dilate[poly1, d^i], where i = 1, 2, 3 to find pattern[br]Enter Rotate[Dilate[poly1, d^i], i r π], where i = 1, 2, 3 to find pattern[br]Enter Sequence[Rotate[Dilate[poly1, d^i], i r π], i, 1, n, 1][br]This Sequence command should work for all polygons.
