NEW PUZZLE
It is called "PYRIX" (retails for $10, I do not have a retail source) and is from:

Enpros Novelty Products, Lorentzstraat 2,
2912 AH Niewerkerk aan den IJssel,
The Netherlands -
tel 31 (0)1803-19133

DESCRIPTION: The puzzle is an assembly folding puzzle based on a size 3 tetrahedron.
The tetrahedron is dissected into 3 regular octahedrons and 11 tetrahedrons (1/3 the size of the original).
These pieces are strung on a thread like a necklace; an octahedron, 3 tetras, an octahedron, etc except
for one position that has only 2 tetras. The octahedrons are threaded on the diagonal of their square cross section.

OBJECT: The faces are colored and the object is to not only assemble a tetra but of course to do it with solid
colored faces, the enclosure says that there are 2 solutions as they have colored and strung the pieces.

PRELIMINARY REVIEW: It took about 1 hour. The puzzle is awkward to manipulate since it falls apart easily.
Doing it on a flat surface and using tape to hold it together seems to be the trick.


Binary Arts produced a puzzle called GeoMorph 12, that was similar in some way.

...its not realy a magic puzzle (by my definition). Just a collection of regular tetrahedrons and octagons strung together on a loop of string. Idea is to place the pieces in the box with solid colours on each face. It is more like a Soma cube than a Rubik cube.

Max.

The same seller sold another one a few days before:

I've noticed them from time to time. This seller seems to have a bunch in nice new-looking boxes. Personally, I wouldn't pay too much for one no matter the condition.
