That's exactly what it is :)  Kepler noted similarities between how 
these platonic solids were nested and the orbital distances of the 
planets.  He published drawings of  this model in a work called the 
Mysterium Cosmographicum.  I think he wanted a real one to be made, but 
I don't think he ever did.
