Stellated Platonic Solid with a Void

This time our assignment was to add stellations to a Platonic solid.  Stellations are additions to a solid that form a point with the number of sides on the stellation equal to the number of sides on the shape to which it's attached.  So, since an octahedron is composed of equilateral triangles, its stellations will have 3 sides.  I chose to work with the octahedron again and this is how it turned out -- pretty, eh?

In addition to stellations, we were supposed to create a void in one side.  This is simply a "hole" dug out of the solid, as you can see here.  I created it by folding a stellation inward instead of out, like the others.  Bristol board.
