Hi Rudl,

> Perhaps someone could give me a advice, may be Torolf höchstpersönlich.

(nee, glaube ich nicht... ;-)) i doubt that Torolf gives any advise any longer, because he helped in the past lost's of people and figured out later that his design ideas were often badly copied and then sold as 3D prints, for example. I can fully understand this and would also get angry when this would happen to me. Especially since those little math sculptures could make it as good jewelry designs...

Regards
Stefan
