Using OpenSCAD, a software for creating solid 3D CAD models, I've created a number of sculptural objects based on recurrences and variations of algorithmically generated geometric forms.
The designs take advantage of the ability to merge and intersect solid objects in the virtual space of OpenSCAD. This allows each geometric form to go perfectly "uninterrupted" in space, weaving in and out of the other forms.
The objects can be 3D printed in a number of materials.
