Hi STEFAN,

Thank you for the information! I am interested in complex geometrical shapes.

I did not know sjoo(R.I.P) had invented linked-star! To me it is really interesting when I think there might be shapes or 3D object that could be invented!

Do you happen to know nice Forums in which people share knowledge about Geometry ( Specially 3 dimensional Geometry) I would like to know more about these objects. for example I just think there are similarities between Celtic knots and Linked-Star but I don't know for sure.

:-)
