Click a thumbnail to see its larger version and description.
A smaller version of the common Meffert Pyramorphix. Made in East Germany.
This is a tetrahedron of 68 mm edge length equipped with 2x2x2 cube mechanism such that each of the three rotation axes runs through the center of two opposite edges. Changes shape while being twisted. Coloured stickers on black plastic. Made in East-Germany 1984 and sold as "Figurenmatch" (weight: 18 grams).
The "Stern" (also made in East Germany) resuses the pieces for this puzzle.
Image 2 demonstrates the size of this version. It has the same size as a Meffert's key chain Pyramorphix but comes without a keychain like Ruby's Triangle.
Image 4 shows a state which is seemingly impossible.
Image 10 prooves that the packages were not uniform.
