The dodecadodecahedron is a dodecahedron with its faces turned into stars and the extra rhombi pushed down. My Dad made one out of Zometools at the Mosaic Fest in Nebraska with Paul Hildebrandt, one of the inventors of Zometools. Paul is interested in the shadows of shapes and this one has so many fun shadows! Check some of them out:
Aren’t they cool? I think they look like those patterns you can make with a Spirograph kit. Paul and I got those different shadows by holding the DDhedron in front of a projector and rotating it.
