Stereoscopic Compound of 5 Octahedra

View this with red-blue glasses, red on the left. Red-green glasses will also work (but not as well). I also have a color version of this, to be viewed stereoscopically with the "look crossed" method.
Mathematica was used to generate the input data for the POV-Ray ray-tracing program. Left and right images were rendered separately then combined using Adobe Photoshop LE.

One step back !
The whole way back !
