One of the headpieces I created for Halloween 2010. This model is based on a 3D scan of my head to ensure a perfect fit, but it also fit well for everyone else who tried it. In the video below, a VRML viewer was used to explore the design and run around in it like a video game. It is fairly sturdy but be aware that your Head Village may be missing a few trees by the time it gets to you.
This is the framework for a work-in-progress. A subdivided dodecahedron provides the basis for this complicated truss. There are circular holes on the vertices, edge-middles and face-centers of the original object. The holes are designed to accept snap-in inserts in three sizes, making it easy to add the additional parts and a pedestal to the sculpture.
