Rolling reuleaux polygons, or spheroforms, are unique 3D shapes characterized by constant diameter and ridges. Despite these ridges, when placed under a book, they maintain a horizontal position much like a real sphere. For more information on creating these intriguing solids using Inventor and Matlab, check out the tutorial at http://wp.me/p3gI7M-2j or watch the video demonstrating their functionality.
