Hi Heiner,

** Your mentioning of T-Splines is interesting, because i am monitoring these for quite some time, but was not able to raise the funds
to get them (Besides they are Autodesk now, which is a company i am not too fond of). **

Clayoo is supposed to be very similar to how T-Splines works, but without the Autodesk association.
