Five tetrahedra fit neatly into the corners of a dodecahedron. See http://www.shapeways.com/model/121250/dodecahedron___5_tetrahed.html by LatexSpikes for a beautiful wirefram example. So, when rolling the compound, it'll always land on five points, like a dodecahedron, and so we can number it like a d12. There are actually two chiral forms of this shape, and this is one of them. Combining both yields another, more symmetrical shape.

No, it's a different shape. It's five tetrahedra overlaid on each other... Here, you can see it better in http://mathworld.wolfram.com/Tetrahedron5-Compound.html and tell that it isn't the same as any of the Kepler-Poinsots. (BTW, my http://www.shapeways.com/model/147284/great_dodecahedron___d20.html is also a Kepler-Poinsot solid. You already have one.)

Mark .. I cant tell ... but is this a Kepler-Poinsot Polygon? http://mathworld.wolfram.com/Kepler-PoinsotSolid.html http://www.dicecollector.com/MINT24_SHAPEWAYS_DIZINGOF_KEPLER_POINSOT_POLYGON_01.jpg
