Curved Diamonds Pattern. The turtle moves from left to right drawing diamonds. There are two functions, one draws a 'spike' perpendicular to the general direction of the turtle. The second function controls the height of each 'spike' gradually increasing it and then decreasing it - to create the diamond.

The additional feature here is the ability to change the spacing between the 'spikes' to change the width of the diamond.
