Distorted vase in OpenSCAD (NEW)

The distorted vase is a 3d printable vase that I designed in OpenSCAD. It’s a small script that I nevertheless want to share with you not because of the vase, there are plenty of nice designs out there, but because the script contains some little tricks. Undoubtedly the vase could have been scripted in many other ways and probably more efficiently too but this example demonstrates nicely to combine polygon, hull and intersection in OpenSCAD to create some neat shapes. How does it work? First we create a number of polygons. The polygon is two dimensional shape in the xy-plane. Next each polygon is transformed into a 3d-shape, the segment in the script, and placed around the origin with the height in the z-direction. The segments are evenly spaced thus creating a star like shape. Now the star-like shape is sliced in the z-direction and the hull operation is used to wrap each slice. All slices on top of each other result in the desired 3d-shape. The coordinates of all the polygons are
